Description zhuoyin 2024-09-14 13:46:35 UTC

Application: plasmashell (6.1.5)

Qt Version: 6.7.2
Frameworks Version: 6.5.0
Operating System: Linux 6.10.9-arch1-2 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.1.5 [CoredumpBackend]

-- Information about the crash:
Normally freshly booted plasma will work, but normally after 1 min usage, plasma crashes very frequently in different ways and generated similar backtrace, below are the observations of how it triggers crashes:

- If I press alt+tab to switch 
- If I right click the steam icon in the tray and hover over to different options
- If I just move around my mouse

I thought it might be nvidia driver issue, but I switched between proprietary driver and open source driver (560.35), the crashing issue persisted

The crashes happened way more often in wayland compare to x11, and sometimes the plasmashell reopen is not even triggered and I need maintain a terminal to start the plasmashell if I need to

The crash can be reproduced sometimes.

Thank you for the bug report. The backtrace looks very similar to cases caused by enabling the QtQuick Vulkan backend, which is not supported.

Please run `kcmshell6 kcm_qtquicksettings` and make sure that Rendering backend is set to Automatic.

Comment 3 zhuoyin 2024-09-14 21:04:24 UTC

Thanks for the advice, I think it's solved, I changed to automatic as you suggested, then log off and log in again, so far no crashes.

Really appreciated
