Description filip.milosevicns 2025-10-27 10:28:48 UTC 
Application: kwin_wayland (6.5.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.0
Frameworks Version: 6.19.0
Operating System: Linux 6.17.4-arch2-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.5.0 [CoredumpBackend]

-- Information about the crash:
Since I upgraded to plasam 6.5 this started happening

After I put my PC to sleep, I turn off one of my monitors. 
Then after I wakeup my PC I turn on that monitor.

This causes kwin to crash everytime.

I use an Nvidia GPU if relevant

The crash can be reproduced every time.
