SUMMARY
Duckstation is a PS1 emulator that has a problem when goes fullscreen on a
Wayland session.
If you try to go fullscreen, the windows is put on the top left of my desktop,
stuck there.
STEPS TO REPRODUCE
1. Open Duckstation, Options->General Settings->Render to Main Window->Disabled
(it's another problem with the program, if you try to render to main window,
it's invisible, you can hear only the sound).
2. Download this homebrew
[https://archive.org/details/magic-castle-2021-01-feb] (it's a community
project, not a copyrighted game, so free to distribute). Unpack it where you
want.
3. System->Start File->Point to it.
4. Try to go fullscreen with Alt+Enter.
OBSERVED RESULT
Windows stuck on top left.
EXPECTED RESULT
Fullscreen.

ADDITIONAL INFORMATION
Duckstation is built from AUR
(https://aur.archlinux.org/packages/duckstation-git) and it uses QT 5.15.3. It
worked around November 2021 but then stopped working.
There is a VERY similar bug https://bugs.kde.org/show_bug.cgi?id=444962 but
Duckstation doesn't use SDL for window management.
I'll add a Wayland Debug log as requested on IRC, it's simply taken by starting
a game and going in and out fullscreen 3-4 times. I've used this from terminal
env WAYLAND_DEBUG=1 duckstation-qt > logfile 2>&1 .
