Description Dawid Kruczek 2024-08-24 19:53:29 UTC

Application: plasmashell (6.1.4)

Qt Version: 6.7.2
Frameworks Version: 6.5.0
Operating System: Linux 6.10.5-200.fc40.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 40 (Workstation Edition)"
DrKonqi: 6.1.4 [CoredumpBackend]

-- Information about the crash:
I'm not sure if it's just my computer or what is happening, but recently Plasma keeps crashing on my PC when I try to interact with panels or desktop (I mean, background - this doesn't affect open windows). So far it happened when I: 
- tried to switch virtual desktop by hovering my mouse over background and using scroll wheel (which is set to change virtual desktops);
- tried to change speakers volume by scrolling on speaker icon;
- tried to change speakers volume using VOL+ key on my keyboard;
- tried to check calendar by clicking on date and time applet;
- tried to open running app's window by clicking on its icon in the system tray;
- tried to copy text using a clipboard applet;
Most of them happened same day. 

Additional info:
Graphics driver is proprietary NVIDIA 555.58.02 (using Wayland)

The crash can be reproduced sometimes.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault

Comment 1 Nate Graham 2024-08-27 18:55:34 UTC

The crash backtrace indicates that the problem is in the proprietary NVIDIA drivers. Note than version 555 is technically a beta version, so I'm not super surprised that it's kinda crashy.

Please report this issue to the NVIDIA folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-graphics/linux. It would be helpful to the NVIDIA developers if you could run nvidia-bug-report.sh and attach the resulting file in your report. Thanks!
