Bug 509840

Application: plasmashell (6.4.5)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.2
Frameworks Version: 6.18.0
Operating System: Linux 6.16.8-arch2-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.4.5 [CoredumpBackend]

-- Information about the crash:
For about the past week or two after I boot into plasma the taskbar freezes and plasmashell starts crashing repeatedly. This doesn't happen every single time, but maybe about 80% of the time. Everything works for about 30-60 sec until the crashing starts.

I have also tried deleting .cache, .config/plasma*, .local/share/plasma which seems to have solved the issue temporarily but when I created a new panel on my secondary screen it started crashing again. That is the core dump that is attached with this report. I will keep testing and updating this issue, please tell me if you have any questions or suggestions.

I have updated to the latest available packages on Arch without change.

Also:

Not sure if it is related but it also takes a really long time for the plasma desktop to load to begin with. This started happening maybe a few months ago but has kept getting worse over time. Is there some tool to troubleshoot this with?

The crash can be reproduced sometimes.
