Bug 1153641

I would suspect a regression from bug 1126754 (the monitor handling code the original patch is based on has changed significantly upstream since 3.8), however:

> Steps to Reproduce:
> 1. On the first screen open gnome-terminal
> 2. Open another window of gnome-terminal
> 3. Maximize the second window

I have not been able to reproduce the issue with these instructions. Can you please provide some more information? What monitor layout are you using (primary on the left/right/bottom/top)? How do you maximize (double-click, shortcut, window decoration button)? How do you open the second terminal window?

I have laptop with two external monitors connected. Laptop lid closed, Primary on the right, secondary screen on the left.

I open two terminals (from the dash) on primary screen and maximize (by shortcut) one of them. It moves left to second screen.

Reproduced in gnome shell and gnome-shell classic - it works with the maximize button too.

Actually the easiest reproducer, I'm seeing now, is open firefox (from dash or menu in classic) - its window blinks on primary and then jumps to second screen.

With fresh user the screens overlap in default configuration and I have to change the display layout - probably another bug.

Florian, 

any progress? I can reproduce too with recent gnome-shell.

Thanks
Tom

No, I have still not been able to reproduce. Maybe that's because I am only testing with laptop + external monitor - does the issue go away for you as well with such a setup?

I'm able to reproduce with just one external display.
Internal laptop screen is primary screen - with the top bar.

Move mouse to external display, open terminal from dash using only the keyboard so the mouse stays put (pressing window key and type "ter"). Maximize the window by pressing F10 - terminal window jumps to primary screen. Seems that moving the window negates the issue.

Move mouse to external display, open firefox from dash - window opens on external display but immediately jumps to primary screen.

Primary still on the right as in comment #3?
(I'm still completely in the dark on this - I still haven't reproduced this with the primary on the left, right, top or bottom)

Assuming F10 should be Alt+F10 (e.g. maximize), then no - still working as expected :-(

Does the same happen if you don't go through the overview, but open a new terminal window via the ctrl+shift+n shortcut? If so, does the problem still happen when you run "mutter --replace" in a terminal (note that you will loose all panels with this - running "gnome-shell --mode=classic --replace" after the test will give you back the interface)

I use fresh user and default display configuration, i.e. primary on the laptop screen, external screen right of primary.

Best reliable reproducer I have is the one with the firefox new window. Open firefox, move its window to external screen and press Ctrl-N - new window jumps to primary. Happens all the time.

I can reproduce it by running just the mutter, mutter-3.8.4-10.el7 is the last good build, mutter-3.8.4-12.el7 is the first bad build.

Thanks, this is helpful information - I've now tracked down the issue and will provide a fixed build once we get all the required flags.

Verified the fix.
