           Summary: Can no longer move windowed fullscreen window to

I can't move my windowed fullscreen app from the default monitor to my second
monitor. It tries to move but after one frame is drawn it reverts back to the
default monitor.

I suspect the regression is caused by 6a2e414d as this is the only relevant
change that came in 10.4 that wasn't in 10.3.

I reverted 6a2e414d and rebuilt 10.4 and now my windowed fullscreen application
won't open its main window at all.

wine output attached.

Could you please give more details about which window manager is being used,
and how the windows are being moved to a different monitor?

This is possibly a window manager specific bug, that needs to be fixed on the
window manager side. Some other window managers (ie: KWin) behaves differently,
and forbid fullscreen windows from being moved to other monitors through the
usual XConfigureWindow requests, and this change fixes cases where the monitor
selection in various game display settings was not effective.

Also note that on Windows it's unlikely possible to move fullscreen windows
manually, and so the behavior now more closely follows it, (though I'm not
saying that we don't want to be more user friendly than Windows).

Sorry, I put the comments on the PR for 6a2e414d.

Here they are;

Environment;

Dist: Ubuntu Noble (24.04)

Kernel: 6.13.5 (ubuntu kernel ppa)

Drivers: Mesa 25.0.2 (kisak ppa)

DE: XFCE 4.18.4 (noble dist)

Windowing: X11 7.7 (noble dist)

Hardware: RX 7600 / Ryzen 5700X3D / 32GB RAM

Also, a note; staging 10.2 was broken for me as the fullscreen window wouldn't
open for it either, so I held at 10.1 until 10.3 came out, and now it seems
10.4 with 6a2e414d reverted has similar behaviour as 10.2.

I'm happy to test code, patches, etc. I'm git and C/C++ literate although my
knowledge of Wine / Windows is limited from a code perspective (but I have done
linux kernel hacking in the past).

Also, if you want I can give you a Wine log for staging 10.4 as well, but I
suspect that it won't log much as it is "working as intended".

I depend on being able to move the full screen windows to alternate monitors
because I usually have two running, side by side.

Oh, and one last comment, the app is in "windowed full screen" mode not "full
screen". I'm assuming that "windowed full screen" is just a window that is full
screen in size but obviously without window decorations.
