Description kleines 2025-03-29 18:33:05 UTC

Application: plasmashell (6.3.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.2
Frameworks Version: 6.12.0
Operating System: Linux 6.13.8-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.3.3 [CoredumpBackend]

-- Information about the crash:
When the system wakes up from sleep, or when it turns on the screen again, plasmashell *consistently always* crashes. This is most likely due to my screen configuration changing during the wakeup / screen-enable sequence and may be related to how the NVidia proprietary driver detects screens during that process. It has also been observed only on Wayland.

The crash can be reproduced every time.
