Thanks for filing the issue!

As this seems to be related to Virtual Desktop, which we do not have to test and confirm the issue. Hence routing to Inhouse team and requesting someone to have a look into this and help in further triaging it.

Just to be clear, this is related to Windows 10's *built-in* virtual desktop functionality, not to some third party virtual desktop utility.

Tested the issue on windows 10 using chrome #70.0.3538.110.Observed that chrome window doesn't remain open.

Steps followed:

1.Opened chrome on multiple desktops in windows 10
2.Logged out>> Turned of Display-port monitor
3.Turned on Display-port on>> Logged in
4.Observed that all chrome windows in all desktops are closed . Launching chrome in any one desktop resulting all the previously opened chrome windows in different desktops are opened in that single desktop.(Rest desktops are empty)

@dictoon: Could you please look into above steps and confirm if anything is missed from our end ?

Thanks!

What do you mean by that exactly?

> Observed that all chrome windows in all desktops are closed . Launching chrome in any one desktop resulting all the previously opened chrome windows in different desktops are opened in that single desktop.(Rest desktops are empty)

That seems even worse than what I'm observing!

Your repro steps are correct. I just test again on a freshly booted up Windows with Chrome 70.0.3538.110 (Official Build) (64-bit). Opened two windows on two different desktops, locked the workstation, turned off then on my DisplayPort monitor, logged in again and both windows were now on the same desktop.

Thank you for providing more feedback. Adding the requester to the cc list.

I am seeing same behavior as above when i just lock the screen, turn off then on the display port and login again.

I am seeing c#4 behavior if i Log out, turn DisplayPort monitor off then Turn DisplayPort monitor on and then login back. 

> Observed that chrome window doesn't remain open - I mean here that when i log out, turn off then on my DisplayPort monitor & log in again i see chrome window is not open in none of the desktops.


@dictoon: Please confirm if this issue can be closed as per c#5.

Thanks!

The issue *cannot* be closed.

I can confirm once more that this bug happens multiple times a day on this (otherwise perfectly healthy) machine.

It doesn't happen to any other application.

As far as I can tell, this behavior appeared in Chrome after the redesign of the window title bar. In other words: this is a *regression*.

I'm happy to record a video if you wish so (with my phone since this involves a log out).

I'm sorry but if you're seeing the same behavior (which is clearly incorrect), why would you want to close the issue?

++ correction in c#7:

I miss read your comment #5- i read it as you are seeing both windows in both desktops (un-shuffled).

I am seeing windows in respective desktops when i just lock the screen, turn off then on the display port and login again..

@dictoon: Please provide us screen-cast for further triaging.

Thanks!
