Classification: Plasma
Product: kwin

coredump from gamescope w/ backtrace
SUMMARY
After the latest version upgrade of KWin (6.3.3.1-2 -> 6.3.4-1) on Arch Linux,
Steam games that have multiple game windows, like a launcher that appears and
then closes before the game launches, will crash after the first window closes.
STEPS TO REPRODUCE
1. Download Trackmania (free) from Steam
2. Add `gamescope -- %command%` to the game's launch options
3. Launch the game
OBSERVED RESULT
You should see the UPlay window appear for a few seconds, and then once that
window disappears the game crashes instead of opening the main window.
EXPECTED RESULT
Gamescope should not crash under these circumstances, and did not crash until
KWin 6.3.4. The crash also does not occur on Gnome.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: CachyOS Linux
KDE Plasma Version: KDE Plasma Version: 6.3.4
KDE Frameworks Version: KDE Frameworks Version: 6.12.0
Qt Version: Qt Version: 6.8.3 (Qt Version 6.9 has the same issue)
ADDITIONAL INFORMATION
Report in gamescope: https://github.com/ValveSoftware/gamescope/issues/1796
I'd recommend using gamescope 3.16.2, as there is a recent regression in 3.16.3
that can present somewhat similarly to this issue.
