Need to re-triage again in multiple win 8 / win 10 systems.

Comment 29 by, Sep 4 2015

Labels: -Needs-Bisect
Unable to reproduce the issue on Windows 8.1 Pro and Windows 10 Pro. Tried on Multiple systems. Used chrome version 45.0.2454.85 Stable and 47.0.2498.0 Dev. Followed the steps below:

1) Enabled Auto hide Task Bar option and launched Google Chrome
2) Maximize the Chrome window
3) Move cursor to location of Window's taskbar (such as bottom of screen.

Windows Task bar showed up when chrome was maximized.

Could some one please try on the latest Win 10 Pro versions and update us with your observations.

Removing Bisect label, will add if required again.

Issue still occurs on Chrome Version 45.0.2454.85 m, Windows 10 Pro version 10240.  Followed steps below: 
1) Enabled Auto hide Task Bar option and launched Google Chrome
2) Maximize the Chrome window
3) Move cursor to location of Window's taskbar (such as bottom of screen)
Taskbar did not show up when Chrome was maximized. Win+T still shows the taskbar as usual.

Good news! I've used Google Chrome for a LONG time but since they can't fix this increasingly annoying problem, I've now completely switched to Firefox. You should try it: awesome!

Problem occurs in windows 7

Comment 35 by, Oct 1 2015

Been happening to me for years, through Windows 10 and 8.1. Issue seems to be caused when using multiple displays and waking from sleep or connecting a new display, or sometimes just by waking from sleep with no additional displays connected. Happens to me 100% percent of the time upon waking the computer from sleep, regardless of displays connected or extensions installed. This really has been going on for far too long to not have gotten a real response yet.

Comment 36 by, Oct 1 2015

Agreed - happens to me all the time on Windows 8.1 and 10, latest Chrome stable build.  Only one monitor.  Seems to be caused when computer wakes from sleep.

This should have been dealt with ages ago.

Comment 37 by, Oct 1 2015

In addition to the problem with the taskbar hiding (which happens on either of my monitors at any time, including after disconnecting my laptop, the taskbar does not hide itself automatically as a result of this.  This has been a major issue since I started using Windows 8, and has continued with 8.1 and 10.  The latest glitch (taskbar not auto-hiding when Chrome has been up) is a 10-specific issue I think.

Comment 38 by Deleted ...@, Oct 1 2015

Really annoying issue. 

Temporary solution for when it occurs for me is to rightclick the taskbar to get the properties, then toggle the auto-hide setting and apply, then change it back to what it was and apply.
Seems to reload the taskbar.

Comment 39 by Deleted ...@, Oct 5 2015

Same here. Taskbar does not show when chrome is maximized. This will always happen after waking from sleep. Toggling auto-hide in settings off, then apply, then toggle on, then apply, will fix it until it wakes from sleep, and then have to do it all over again.

Chrome: Version 45.0.2454.101 m
Windows 10 with all updates applied.

Comment 40 by, Oct 8 2015

Basically, Chrome ides the pixel needed by the taskbar to show up. On any other windowed program (well, beside Opera since it's a Chrome clone), even if your taskbar is auto-hidden, you see a small blue line.
It is, in fact, Chrome using some Windows functionalities in a wrong way.

This issue is also extremely inconsistent, it's here 80% of the time. I haven't been able to find why, sometimes, the taskbar shows.
And extremely annoying, it prevents other programs to pop notifications.

Comment 41 by, Oct 8 2015

8 Months and no acknowledgment or solution

Comment 42 by, Oct 8 2015

We had noticed this in Win 10 preview builds but then it disappeared again and we couldn't reproduce it anymore (I can't reproduce it on either of my machines right now, see also #29 above). Sounds like it's flaky and only happening under some circumstances that we don't understand yet. Adding scottmg@ and jschuh@ for triaging/ideas.

Comment 43 by, Oct 8 2015

It happens on all my machines and all workplace machines (50+) but its not constant, you need to use it for 2 weeks solid to get the feeling for how bad it is, as I type it is currently showing the taskbar but it wasn't 20 minutes ago.

Comment 44 by Deleted ...@, Oct 13 2015

+1 having this issue since i turned autohide for windows taskbar on

Comment 45 by Deleted ...@, Oct 13 2015

Found the way how to reproduce the issue on my PC. I have two displays in clone mode (monitor and TV via receiver). Hit Win+P to select single display mode, then restart Explorer process. Open Chrome in maximized windows and taskbar works fine. Then hit Win+P to select Extend displays, after that again hit Win+P to select Clone displays. Click mouse somewhere in browser window and taskbar hides forever.
Windows 10 10240 Chrome 45.0.2454.101 m.

Comment 46 by Deleted ...@, Oct 16 2015

I have the same issue. It's annoying! I had it on Windows 7, but now that I'm on Windows 10, it's gotten much more consistent, and unmistakabely linked to Chrome and Chrome alone. I hadn't noticed the wake from sleep pattern before, but it does seem extremely consistent with what I experience. I hope Google fixes it.

same problem, windows 10, duel monitors, taskbars not show only in chrome (update to current version) 
please address

Comment 49 by, Oct 24 2015

The task bar won't show on my PC when Chrome is full screen. I have three monitors attached but only one is normally used. I have Windows 10. The taskbar shows when the windows key is pressed. This problem started when I upgraded from Windows 7 to 10.

Comment 50 by Deleted ...@, Oct 25 2015

I also have an issue just like the others reported. Windows 10 with dual monitors in extended mode and taskbar set to hidden. 

Chrome does not allow me to pull up the taskbar. It can only be pulled up with the Windows key. It works fine with other browsers and programs, Chrome is definitely the one with the issue.

Comment 51 by, Oct 27 2015

Almost same configuration here:
Dual monitor (extended mode)
Taskbar set to hidden
Chrome version is 46.0.2490.80
But my taskbar is on the side instead.

Chrome doesn't lets the task bar to show as long it is maximized. But the other windows on my desktop does.

Comment 52 by, Oct 28 2015

Win10 tablet (no mouse). With the taskbar autohidden I cannot bring it up by swiping up from the bottom of the screen if Chrome is maximized. No other apps have this same problem, even the "new tile" apps don't have this problem.

Comment 53 by Deleted ...@, Oct 30 2015

This is a Chrome issue and has been around for far too long, it really is about time that it was fixed. If a similar thing occurred in commercial software it would have been sorted immediately. So come on Google, get it fixed, it's long overdue.

Comment 54 by, Nov 1 2015

Same issue on Win 8 and now also on Win 10 after upgarde. This happens only with Chrome maximized window.

Comment 55 by Deleted ...@, Nov 4 2015

I was able to fix this issue by uninstalling Chrome, then reinstalling the 64 bit version. I'm not sure if it was the reinstall or the 64 bit part that fixed the issue, but it looks like it's not happening any more. Hopefully this helps someone else in this thread as well :)

Comment 56 by, Nov 5 2015

I did the same thing uninstalled and installed 64bit, I didn't help, the problem is still here ,
setup similar to above with 2 monitors. I didn't restart the computer yet but I doubt it will help.

Comment 57 by, Nov 5 2015

Reinstall of browser does not resolve.  Issue was apparent for me on brand new install of Windows 8.1 and Chrome (and after upgrade to Windows 10).

Comment 58 by Deleted ...@, Nov 5 2015

This is a transient issue. It can be fixed by turning autohide on and off, and also by killing and restarting the explorer process. This doesn't work all the time though

Comment 59 by, Nov 11 2015

I've had this problem for at least a year. From Windows 8, and now 10. Every fix mentioned above is only works for a short period of time. I can't tell what causes the problem to re-appear, whether a reboot, window resizing then back to maximized, but it usually doesn't take more than a hour for the bug to show up again. One point that I learned from other posts in this forum, that my experience echos - I use two monitors, and this bug only occurs on the main monitor. If I move the Chrome window to the secondary monitor, and maximize the window, the taskbar pops up as it should. If I move it back to the main monitor (maximized), then I have to hit Win+T to get the taskbar to show.

Comment 60 by, Nov 11 2015

Do those of you impacted by this have any desktop enhancers or custom window manager utilities installed?

Also, to be clear, are those impacted by this 1) maximizing the Chrome window via the control in the top-right corner of the Chrome window's title bar, 2) entering fullscreen mode via F11, or 3) entering fullscreen mode via an item in the content of a web page (e.g., the fullscreen control on YouTube)?


Comment 61 by, Nov 11 2015

To answer your questions:

I have not installed any window manager utilities. Just native Windows 10.
When I say maximize, I am not referring to Full Screen mode (F11), I am
referring to the native Windows Maximize icon/button that is immediately to
the left of the Window Close "X" icon in the top right corner of every
Window. This Maximize icon is replaced by the "Restore Down" icon whenever
the window is maximized.

Comment 62 by, Nov 11 2015


No desktop enhancers or window managers.  Straight Win10.

Window maximized via top right maximize button.

Comment 63 by, Nov 11 2015

Same as above but win 8.1

Comment 64 by, Nov 11 2015


No desktop enhancers or custom window manager utilities: native windows 10
upgraded from 8.1 (same bug existed) on a Dell XPS 13.
Problem appears after maximizing the Chrome window via the control in the
top-right corner of the Chrome window's title bar (not full screen or F11)
I am currently not using auto-hide because of the bug....extremely


Comment 65 by, Nov 11 2015

same here, straight win 10, switched to FF for now

Comment 66 by, Nov 15 2015

I think that has the proper description of the actual problem.

Basically, the browser hides 'the pixels' the OS needs to trigger the taskbar.

Is there a way to have Chrome maximize but with, let's say, one less line at the bottom of the screen?

Comment 67 by Deleted ...@, Nov 17 2015

The issue can be reproduced easily on both of my laptops with win10 upgraded from win7 (one of win10 installations was performed as clean install). No enhancers or whatever.
The issue is reproduced as follows:
- you have only one display attached (the screen of the laptop for example)
- open chrome in maximized window
- now connect a second display in extend display mode (not duplicate)
Back on your first screen where chrome is full screen - no win taskbar is shown when you move a mouse to where the taskbar should be (left side in my case).
This stays even after you isconnect the external display.
I use chrome 46.0.2490.86 m now.
The only way to get it back working is disable auto-hide for the taskbar, apply, then enable it again (or reboot obviously).
This is really annoying on my work laptop when I go to meetings and back to my workplace, where I have an external monitor. Please release some fix for this.

Follow these steps to move the position of your taskbar and move it back again:

- Minimize Chrome or close it so you can see you taskbar.
- Right click on the taskbar and select “properties”.
- Change the position of your taskbar from the bottom of your screen to the right of your screen.
- Click on Apply or OK and close the dialogue box.
- Right click on the taskbar again and select “properties” again.
- Change the position of your taskbar back to the bottom.
- Click on Apply or OK and close the dialogue box.

That is it. After I did that, my taskbar worked fine in Chrome. I’m not sure if this will be a permanent fix or not, but it seems to be working for now

Comment 71 by, Nov 22 2015

It will not be a permanent fix. Any change of the taskbar properties makes
the issue go away temporarily, or until the next time you open Chrome.

Comment 72 by, Nov 22 2015

How do i unsubscribe to this problem that has been reported for EIGHT MONHTS now...? I'm now content w/ Firefox.

Author: ananta <>

Fix for a long standing bug in Chrome windows with the auto hide taskbar.

This bug reproduces at times with multiple monitors and occurs when our attempt to
retrieve the taskbar edge information via the ABM_GETAUTOHIDEBAR appbar message fails.
msdn recommends using the ABM_GETAUTOHIDEBAREX call with the monitor rectangle for the multiple
monitor case. However that does not work.

The following fallback does work though.
1. Query for the auto hide status of the taskbar.
2. Retrieve its position and check if the edge information returned in this call matches the
   edge we are looking for. This along with the monitor check is sufficient.

BUG= 472139 
TEST=Set taskbar to autohide. Connect multiple monitors to the machine and start chrome on the
primary monitor and attempt to reproduce this case. If it does not repro then move chrome to
the other monitor and attempt the test case. If that fails, disconnect the secondary monitor
exit chrome and try. One of these cases should reproduce the problem.

Comment 76 by, Nov 29 2015

I too cannot see the fix? stated in #74

Win 10, maximise via traditional button in right hand corner, no mods.

Comment 77 by, Nov 29 2015

Cannot see a fix either !
This problem has been around for so long it is just ridiculous ?

Comment 78 by, Nov 29 2015

The fix is currently live in the canary channel. It would be great if those if you impacted could try it out and let us know if it's fixed there for you. You can find the link cks to install canary here: Thanks.

Comment 79 by, Nov 29 2015

Installed the Canary channel. So far the fix is working, I have dual screens and the taskbar works on both. Left my Laptop to sleep, then came back, and there are still no issues when left in maximised mode. For me the issue seems to be resolved! Thanks!

Comment 80 by, Nov 30 2015

Installed Canary build for Windows (64-bit) and problem is solved when
using two external screens with my Dell XPS 13 and when using only internal
screen. Thanks for the fix.
When is this going to the standard Chrome version?

Comment 81 by, Nov 30 2015

Talked too fast: after docking the computer back with the two external
screens the problem is there again...
The Win 10 taskbar set to auto-hide appears on the main screen but refuses
to appear on the secondary screen when Chrome Canary is maximized.
It seems the fix is only PARTLY solving the issue.

Verified the issue on Latest Dev# 49.0.2587.0 on Windows and could not reproduce the issue.
@Jmruthruff -- Could you please re-check on your machine and provide the latest behavior.
Thanks in Advance.

Comment 84 by, Dec 10 2015

Chrome and Firefox take control of the task bar when maximized. Such that, when Chrome/Firefox is in front, clicking another open window from the task bar, that window will not come to front, (just flashing in the background) as long as Chrome/Firefox is in front. If any other window than Chrome/Firefox  in is front, clicking other open windows from the task bar works as expected. It seems Chrome and Firefox somehow cause this problem and share the same behaviour.

I tried many solutions presented on line such as changing keys values in the registry, changing the theme, making Chrome and Firefox run as administrator. All these solutions require restarting and then they fix the problem. However, after some time or when restarting again, the problem returns. It is really annoying.

Comment 85 by, Dec 11 2015

Hi Miloud

It would be great if you could track how Chrome gets into that state where when maximized no other app can come to front. 


Comment 86 by, Dec 11 2015

Hi Ananta, 

I noticed that Chrome gets to that state in particular when I use Windows 10 theme (the main theme that comes with Windows 10). When I use the theme provided by my laptop brand (mine is Toshiba theme), the task bar works fine (at least for a long time). It looks like something has to do with ((browsers window)) especially Chrome and Firefox (not Microsoft Edge which works fine always) and the ((themes)). The background of the Windows 10 theme I mentioned is in the attached file. This theme specifically cause Chrome to not allow focus or bring other open windows to front, but many other themes do as well. It might be helpful to check how the mentioned Windows 10 theme is handling desktop icons, windows, and file exploring in general and in specific Chrome or browser window, and so find out the root of the problem.

I have this same problem temp work around is to change an option with the taskbar like move it or enable disable auto hide, all of these work arounds are temporary and the problem returns next time you open chrome. I have had this issue for years and currently have it on the windows 10 pro version 1511 (OS Build 10586.29)

Comment 88 by, Dec 13 2015

This happens on Win10 for me with Chrome, but it is intermitent. However it
also happens with qBittorrent, again intermitently and I believe it is
triggered by Chrome.

Force a WM_NCCALCSIZE to occur when we receive a WM_DISPLAYCHANGE notification.

The WM_DISPLAYCHANGE message is sent when monitors are added/removed. Forcing a WM_NCCALCSIZE
message to occur ensures that autohide data is recalculated which ensures that autohide taskbars continue
to popup when we hover near the bottom of the window when chrome is maximized.

BUG= 472139 
TEST=Connect two monitors. Run Chrome on one monitor and maximize it. Set the taskbar to autohide.
     Observe that taskbar pops up when we hover near the bottom. Now disconnect the monitor where
     Chrome is running. The window should move to the other monitor. Observe that the autohide taskbar
     continues to work.

Hence adding TE-Verified label to the bug.


Comment 93 by, Jan 9 2016

I get the same issue with Windows 10 and Chrome 47.0.2526.106 m and a single monitor only.

Can be reproduced by having the taskbar on Auto-hide and putting any YouTube video to fullscreen. Once you go out from YouTube fullscreen, the taskbar is hidden behind Chrome and can't be put to front, unless you 'Restore Down' Chrome from Maximized window, click once on taskbar, and maximize Chrome again.

Comment 94 by, Jan 9 2016

Yup that works... or rather Chrome does not work when I click back to a
previously opened tab . taskbar.
That proves the problem is real.

Comment 95 by, Jan 9 2016

The problem is back,  and I haven't changed chrome since I had the problem fixed,  but I know windows 10 has had an automated update since.  The problem seems to occur now after full screening a video on one of the monitors.

This issue dates back to Vista and had continued in every progression of Windows since.
Not to mention it was merged into a ticket that had apparently erroneously been marked fixed??

Comment 101 by, Jan 27 2016

I like the completely nonsensical bug statuses: 

"Needs Feedback" -> You have 7 years of feedback
"Hotlist-WinFixit2015" -> It's 2016 already
misc "Verified" -> It has been verified by people for seven years

Comment 102 by, Feb 3 2016

This only occurs for me when I plug into my extended monitor(s), then continues when I unplug and use laptop only. Clearly, there is some issue with monitor extension. 

Since this problem only occurs with Chrome (no other non-Microsoft applications), there is likely something wrong on Google's end. Honestly, even finding this forum was difficult, so I imagine there are many others suffering this problem silently. We are the determined minority.

Comment 103 by, Feb 5 2016

I only have one monitor and this issue happens all the time. It's the most annoying thing about Chrome and constantly makes me question why I use this stupid browser in the first place when the Chromium team is clearly too incompetent to fix one single issue! Reminds me of the disappointed feeling I had when Chrome was first released and had no middle mouse button scrolling feature until a bunch of releases later.
Really if this issue hasn't been fixed by now when it's been verified several years, I'm wondering WHAT THE HELL the people behind this app are doing day in and day out. So friggin' unacceptable. Does Chrome really expect people to have the patience to deal with this issue for years and years on end? If it doesn't get a fix soon, I'm uninstalling, and maybe reconsidering my commitment to other Google paid services I use. I don't want my money going to a bunch of devs that apparently don't do squat.

Comment 104 by, Feb 5 2016

And no, this issue is NOT FIXED, as the status of this bug says it is. Change it immediately!

Comment 105 by, Feb 5 2016

Same problem with external monitors and when chrome is maximised

Comment 106 by, Feb 9 2016

Same here. Windows 10 Home 64 bits. It also happens to me with Firefox. No other apps (Notepad++, Spotify, Acrobat Reader, ...) showing this issue until now.

If a press "Windows" key, taskbar shows but, if I then press menu icon o move the mouse over a window preview and keep it there, the taskbar hides after some milliseconds (Chrome gets focus again)

Author: ananta <>
Date: Tue Feb 23 21:18:09 2016

Reduce the fullscreen window height by 1px on activation loss and restore it back on activation gain.

This is to workaround a bug/behavior of the Windows taskbar, where in it does not stay as topmost window when a window
on a thread which has a fullscreen window is active. The symptom observed in this case is that the windows on the same thread
as the fullscreen window end up obscuring the taskbar or cause autohide to not work.

The other changes in this patch are as below:-
1. When the bounds of the WinWindow class which serves as
   the PlatformWindow for the WindowTreeHost instance
   change, we don't activate it if the underlying HWND
   is not visible.

2. The WidgetTestInteractive.ViewFocusOnHWNDEnabledChanges
   test explicitly shows the WindowTreeHost instance which
   ensures that the HWND is visible and activated.

Use the MonitorFromPoint API for the cursor position to cover cases where the MonitorFromWindow API fails.

In some cases the MonitorFromWindow API for the taskbar fails to return the correct monitor. Examples include the autohide
taskbar on the left of the secondary monitor or the right of the primary monitor. This causes maximized Chrome windows to
draw over these taskbars.

Fix is to use the MonitorFromPoint API for the cursor position which seems to work for these cases.

Tested the issue on Windows 8.1 dual monitor using 50.0.2661.11.Observed that the window moved to other monitor and the auto hide task bar continued to work when disconnected the monitor where chrome is running.

Marking it as TE-Verified.

I would just like to add I have been having this issue for about 4 years now on my laptop, using only one screen. I do also experience on my desktop with 3 screens.

So, i've also had thise issue since I started using chrome, a couple months back.
My current version is 51.0.2704.103 (64-bit), with windows 10 pro version 1607 build 14393.447

i do NOT use any desktop enhancer or anything else like that.

the issue is only triggered with chrome, AND IT ONLY HAPPENS WHEN A WINDOW PREVIEW/PEEK/THUMBNAIL pops up (from hovering over the taskbar).

That is a detail i have not seen mentionned yet. As long as I don't trigger a window preview by hovering long enough over it on the taskbar, the taskbar will appear and autohide normally. But the instant a window preview pops up, the taskbar disappears (it doesn't simply slide off, it instantly disappears).

Something else interesting to note : triggering a preview pop up while in another software (let's say task manager) will cause the issue to appear when switching back to chrome even though the taskbar still functions normally while that other software is focused.

I cant believe this hasn't been fixed yet! It has been over 7 years!
Windows 10 dual monitor vanilla install. Taskbar is set to Autohide and will not raise when chrome is on top!

54.0.2840.99 m (64-bit)

Status is NOT fixed!

Will this issue ever be fixed? Still happens here on Windows 10 Education 64-bit + Chrome 57.0.2987.98 64-bit + 2 displays. It's enough to minimize and maximize Chrome back, and taskbar is gone under Chrome window - totally frustrating!

Comment 116 by, Mar 25 2017

This issue still exists. Windows 10 Professional 64-bit and Chrome (Version 57.0.2987.110). Attached to two displays (PC monitor via DVI and HDTV via DVI to HDMI cable). Only using a single display at one time.

I have this issue for years now and I'm struggling with it as well. This issue only appears when Chrome is maximized. ANY OTHER PROGRAM being maximized does NOT block the auto-hide taskbar to appear if I want to (by hovering mouse to the edge of the screen).
All I could do is to restore chrome and drag the window as far as possible to the screen edges to mimic maximized mode.
And one more thing: this issue does NOT happen all the time!
Windows 10 (1703, build 16179.1000), SRWare Iron 56.0.2950.1 - but this issue goes far back in time to versions aka 4x.x.xxxx.x)

Is this behavior by design to monopolize the entire desktop area?  If so, just state and close this issue.  If not, will Chromium team please give us a time frame as to when this problem will be fixed?

The lack of any detailed response by the Chromium team is most annoying  A more thorough response to the problem identified is long overdue.

This bug still exists in Version 64.0.3282.140 (64-bit). On Windows 10 Home - 1709. It has existed on/off for years and will occasionally spontaneously resolve for months at a time.

I have dual monitors attached via Display Port and keep an auto-hidden taskbar on both. This issue only occurs on the "primary" monitor. 

I have attached a video example of the bug occurring. The scene with this ticket in view is the monitor with the problem; the scene with OBS and google open is the monitor working as intended. Note the difference.

I do not have this issue with *any* other application.

This is such a silly bug! how can it not be fixed in 3 Years!

Comment 121 by, May 29 2018

This bug exists in Chrome version 65.0.3325.181 (Official Build) (64-bit)

Feels like Chromium team will never fix this bug, so disappointing.

I am running Chrome Version 68.0.3440.106 (Official Build) (64-bit) alongside Chrome Canary Version 70.0.3527.0 (Official Build) canary (64-bit). Chrome Canary prevents the Windows taskbar to open when maximised and only on the primary screen and not on the secondary screen. But the other Chrome works perfectly on both screens and does not prevent the Windows taskbar from opening up.

Windows 10 Version 10.0.17134 Build 17134

I have had this issue recently, I am using Chrome 70 (Dev).  However, this is not an issue with Chrome 68 (Stable).  Again, this only occurs when chrome is maximised. Version info is attached.

I would like to point out that I am using a single screen laptop with windows 10, although it has not been updated since last spring.  I would also like to point out that I can not resize a maximised window, without unmaximizing it and resizing it.
