KWin GDB backtrace as per community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

SUMMARY
KWin stops rendering anything on the screen and locks into 48 FPS when running any GPU-intensive applications fullscreen. Critical because reliably reproducible and affects everyday activities.

STEPS TO REPRODUCE
1. Start application
2. Expand it to fullscreen

OBSERVED RESULT
KWin doesn't render anything, but sound is present, and system is responsive via SSH. amdpu_top shows 0% utilization.

EXPECTED RESULT
Stuff works as expected

Please attach KWin's log:
> journalctl --user-unit plasma-kwin_wayland --boot 0
after triggering the issue (or boot -1 if you reboot first)
