experience the same, Win 10, high res internal display and 1 external monitor

I am experiencing this issue on a Macbook Pro 2016 running Windows 10 (retina display + 2 external monitors). I do development on this machine and changing up the hardware or zoom settings on the primary display is not an option.

This might be the same as  issue 656730 , but that one doesn't mention minimizing so I'm not sure.

I tried the repro steps documented in  issue 656730  and get the black bars. I had not tried that before. I also get the black bars by minimizing and then bring the window back as stated in this ticket. If you resize the browser window the black bars go away.  I have a feeling this is the same issue.

Saw this today on Win10, Chrome 56.0.2924.87.

I was using my laptop without a display, closed the lid, a few min later connected a display. Laptop is at 200% and exteral monitor at 100%. Resumed from sleep, then my secondary profile (which was at least backgrounded... possibly minimized?) popped up a notification that an extension had been removed automatically, I dismissed the notification, and then noticed the black bars. Now they're on all my windows as long as the display is connected.

This happens to me too.

I've having TV Samsung 4K + LG Monitor.
I minimize Chrome, restore it back and bam, black bars.

Same problem here.

I have the same problem. 2 monitor setup on windows 10 with chrome Version 62.0.3202.94 (Official Build) (64-bit).

One monitor is 100% and the other 200% scaling. Chrome produces black bars, that disappear when maximizing the browser window. 

I also have this problem. Win10 1709. Chrome Version 63.0.3239.132 (Official Build) (64-bit). No other app (such as Outlook, Excel, IE, Evernote, etc.) has the issue.

I have two screens: a 4K laptop screen with text scaling set to 300%, and an HDMI-connected external 2560x1080 monitor with 100% text scaling. The issue appears only on the external monitor. Resizing, or maximizing and then restoring, Chrome fixes the issue temporarily. Minimizing and then restoring Chrome causes it.

As this issue is related to Laptop to Desktop connectivity, TE doesn't have connector to test this issue, hence adding label as TE-NeedsTriageFromHYD for further triaging this.

Thanks!

This looks similar to Issue 736364, hence merging into it.
Please undo it, if it not the case

Not sure this is the same issue as 736364 because I cannot reproduce the full-screen problem described in 736364 but I have borders when not full-screen, exactly like described in this issue.

There are more relevant issues that this might be a duplicate of:
-  issue #631212 
-  issue #656730 
-  issue #426656 

I'm having the same issue, I have one monitor that is 4k and has text scalling set at 200%, and other monitors that are 1080p set at 100%, chrome has black bars when minimized and reopened. 

This issue is definitely not a duplicate of issue 736364, I do not have the same problem when in full screen mode as described in 736364. The three black bars occur in windowed mode as well as maximized mode not full screen.

I'm having the same problem... 

Using 1080p @ asus vg248qe (100% scaling )

4k TV Samsung 55MU6655 4096*2160 ( 300% scaling)

Chrome version 66.0.3359.181 (Compilação oficial) (64 bits)

a fix would be good
