Hello, I'm unable to reproduce the issue with the instructions provided. Could you please specify or provide a screenshot of your browser's settings? Also, were you using any extensions prior to updating (In Version 55)? Thanks.

apologies, specs here:

OS Version(s): 10.0 , 7.0 (2 computers)
chrome version: 56.0.2924.87 (64bit)

I've attached a couple of PDFs with the set of extensions.

I'm guessing that it is somehow linked to 'restore sessions' code, so could be affected by Session Buddy.

Don't have time to play around with that right now, but will try to get to some experiments later ...

The issue with the extension session buddy is reproducible via the following:
- open any number of tabs (atleast one expanded and one minimized), ensure the session is saved in the session buddy extension
- close all windows and re open chrome
- click session buddy icon and select "open tabs in respective windows"
- observed all windows restored in open state

It would seem that this is not an issue with chrome, but rather the fact that the extension session buddy does not track state of a window/tab (minimized or open), and only tracks windows/tabs and their associations to each other in a given session (tabs of the same window vs separate windows). Maybe someone else can confirm but this may be an issue better put to the provider of the extension in the form of a feature request. Take care!

Ah - but I didn't actually do anything with Session Buddy. This happened directly from Chrome Launch.

Note that I only use Session Buddy as a precaution, because I've had problems with Chrome losing sessions in the past. It's been a while since that happened though.

Note also that I typically do an explicit 'Exit' of Chrome before shutting down the system, so I rarely have to do an explicit 'restore session' in Chrome. Again, just a precaution ...

Ok, so I did a straight Exit from Chrome, then relaunched it, and took some screenshots:

1: Before: just one window open (Chromium blog), along with the pop-up menu of open Chrome windows from the Chrome icon in the task bar.
2. After Exit and relaunch: all Chrome windows open.
3. After going through and minimizing them all, I also noticed that the order of the windows was messed up, so took another screenshot of the open window list.

Unfortunately, I just checked the screenshots, and it appears as though the Chrome open window list wasn't captured in either #1 or #3. So I deleted #3. Oh well ...

Hope this helps ... Ian

Just to check, I then removed Session Buddy (by right-click on Session Buddy icon, then 'Remove from Chrome ...'), and checked that it was gone from the extensions list.

Did another Exit and relaunch, and same thing happened.

Curiously, the shifting around of windows is limited, and almost certainly not random. Although I'm not sure of the pattern, it looks as though perhaps just one recently accessed window gets moved to the front of the list.

Unable to reproduce the issue on Windows 10, Mac 10.12.2 & Ubuntu 14.04 with chrome stable version (Reported version)-56.0.2924.87 & latest canary-58.0.3010.0 as per below steps:
1. Choose option ' Continue where you left off' in Chrome://settings page
2. Launch chrome
3. Open 3 different URLs in 3 different windows.
4. Now Exit chrome & relaunched again
5. Observed all the previous windows displayed successfully with correct order.

Please find the attached screencast for reference & let us know if we miss any steps to reproduce the issue.
Thanks!!

Attaching screencast here.

Thanks for checking this out - and the video was a nice touch. What tool did you use to get that?

Anyway, the one thing I noticed that wasn't entirely convincing was that the main window you used was maximized, so since it was the last one active, even if the other windows were not minimized after the relaunch I would expect them to display underneath it instead of on top. So the video doesn't seem to totally prove that they stayed minimized - unless I'm missing something ...

With response to Comment#11,followed below steps on Windows 10 using chrome Reported version-56.0.2924.87 and latest Canary-58.0.3011.0
1. Choose option ' Continue where you left off' in Chrome://settings page
2. Launch chrome
3. Open 4 different URLs in 4 different windows.
4. Minimize all the windows & exit from the main window
5. Relaunched chrome 
6. Main window launched first & all the other windows were minimized ( we can see hovering on chrome icon on the task bar)

Please find the attached screencast for reference & it would be better if you provide us the screencast of the exact issue for better triaging the issue further.
Thanks in advance.

Just thought I'd let you know that I'm working on getting a screencast, but my initial attempts have been giving me files over 80 MB! Working on finding ways to reduce that ...

 Issue 686772  has been merged into this issue.

Hi, I am the creator of issue 686722 that was merged into this issue in comment#14. Please find attached a screencast. I have 2 chrome windows open on the desktop, with ~100 minimized. After closing chrome and reopening it, all 100+ windows open on the desktop.
This erratic behaviour started directly after upgrade to 56.
To the shuffling of open windows mentioned in #8: imho this is perhaps related, but different issue as I noticed it some versions of chrome ago, not starting with 56. It appears randomly to me.
But the documented behaviour in screencast happens 100% of the time and it is a real pain.

As per comment #13, 

@ianfarbrother-- Could you please update the issue , with your observations.

Thanks!

Unfortunately, I haven't had time to really work on the screencast issue, and since comment #15 confirms that "it's not just me", and has a screencast, I hadn't prioritized it.

I can confirm that on my system, this is still totally reproducible.

Hope this is sufficient for now ... Ian

Thanks for the feedback removing "Needs-Feedback" label.

Using the per-revision bisect providing the bisect results,
Good build: 56.0.2897.0(Revision: 426673).

Thanks!

hdodda@, could you share your repro steps on linux?

I tried on TOT with:
1. Choose option ' Continue where you left off' in Chrome://settings page
2. Launch chrome: out\Browser\chrome --user-data-dir=/tmp/testc/
3. Open 4 different URLs in 4 different windows.
4. Minimize all other three windows & exit (ctrl-shift-q) from the main window
5. Relaunched chrome: out\Browser\chrome --user-data-dir=/tmp/testc/

I can only see this:
Main window launched first & all the other windows were minimized.

Thanks!

It is likely my CL induces the problem. If I can repro on Linux, that would be very helpful!

I could not repro on neither windows nor linux on tot. hdodda@, could you list your repro steps/details on tot, as you mentioned M-58?

assign back to hdodda@ per #20

Just updated today to Chrome version 57.0.2987.98, and thought I should let you know that the problem still occurs.

I later installed the new Windows 10 update, and the problem still occurred after that also - although I didn't really expect that to make any difference.

Ian

Tested on ubuntu 14.04 using chrome M59 #59.0.3047.0 and issue is still reproduced.

Followed steps :

1. Launched chrome and opened different new windows .
2. Minimized few windows and on main window , ctrl+shift+q (exited chrome).
3. Relaunched chrome and observed that all the minimized windows are opened in background.

Attached screencast for reference.

Thanks!

OK, I can reproduce it now. With
1. Choose option ' Continue where you left off' in Chrome://settings page
2. Launch chrome: out\Browser\chrome --user-data-dir=/tmp/testc/
3. Open 4 different URLs in 4 different windows.
4. Minimize all other three windows & exit (ctrl-shift-q) from the main window
5. Relaunched chrome: out\Browser\chrome --user-data-dir=/tmp/testc/

I have to repeat step 5 two times to see the bug.

Just thought I'd mention that problem still continues after update to Chrome Version 58.0.3029.81.

Wondering if there has been any progress towards fixing this?

Thanks ... Ian

Well, I'd been thinking of asking whether any progress was being made on this, since it has been a considerable time without comment. Anyway, today something changed !!!!

I updated to Chrome Version 61.0.3163.79 (Official Build) (64-bit), and the problem seems to be MOSTLY fixed now. The reason I say 'mostly' is because there still seem to be some oddities floating around.

First: the only window showing when Chrome initiated the update was the Help/About window. I had minimized all the rest. However, a couple of windows started appearing, and I went and minimized them as I've found that aggressively doing that as they appear seems to work a lot better than just leaving them to sort themselves out.

Anyway, then I got the very pleasant surprise that the rest of the windows seemed to stay minimized !!!

So far, so good. However, odd things seem to have gone on with Chrome's History. I noticed this because I had closed a few windows before initiating the relaunch, and went to reopen one of them from the 'Recently Closed' list. It wasn't there - and instead, I found that Chrome seemed to have put some of the existing windows (in at least one case with 11 tabs) into the recently closed list during its relaunch. I opened this one, and found that I now had two copies of that window.

So I went and looked at the rest of History. Seems that Chrome somehow put a whole bunch of windows in there that I had not looked at. I had a bit of difficulty getting the History list in an uploadable form (I'll comment on that later), but by virtue of Printing to PDF a number of single pages I was able to illustrate the problem. So now I'll attach those 5 history files:

Notice that there are a bunch of entries starting at 3:42 in History5.pdf, and extending through at least 3:44 in History1.pdf (and quite possibly through 3:47 - although these might have been from the windows I minimized after the relaunch), and I definitely had NOT looked at these. So they were obviously put there by Chrome as part of the relaunch process.

Ok - so that's the basic outline of things regarding the main problem. I'm VERY glad that progress has been made on this, but obviously there is still a bit of work to do.

So now just a couple of comments about being able to get History to upload. My first thought was to just Save the page. Unfortunately, that just produced a blank page.

So then I tried to Print it, and save it as a PDF. Unfortunately, instead of printing the whole page, it would only print one page at a time. Quite a hassle !!!

So that is why there are 5 separate pdfs instead of just one.

Anyway, thanks for the progress so far - Ian

Just letting you know that the problem seems to be fixed. I haven't seen it occur for quite a while now!
