Description Aaron Bockelie 2024-12-01 01:39:42 UTC

Application: plasmashell (6.2.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.0
Frameworks Version: 6.8.0
Operating System: Linux 6.12.1-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 6.2.4 [CoredumpBackend]

-- Information about the crash:
This happened after unlocking my workstation after leaving if for about 2 hours. I have a shader wallpaper for the lock screen. It behaved normally until I successfully enterned my password. Then, only the application windows and no KDE desktop was available. I am using a single display at 7680x2160 (32:9 ratio) monitor. I have noticed this ratio and resolution seems to push the system a bit.

The reporter is unsure if this crash is reproducible.
