Description hovercraft 2020-12-20 04:13:11 UTC

Application: plasmashell (5.18.5)

Qt Version: 5.14.2
Frameworks Version: 5.75.0
Operating System: Linux 5.9.14-100.fc32.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 32 (Thirty Two)

-- Information about the crash:
- What I was doing when the application crashed:
Just woken up the computer after suspend

- Unusual behavior I noticed:
Usually parts of screen contains garbage after suspend/wakeup, most often these are application and folder link icons on the desktop.
Also sometimes plasma desktop crashes shortly after wakeup.
This happens with any version of plasma and any version of Linux operation system, including Fedora 32 and Ubuntu 20.04LTS.
This situation manifests itself on any computer where any model of Nvidia graphics card installed.

- Custom settings of the application:
There is nothing special to say.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Any chance you can upgrade to Fedora 33 and test again? Or better yet, Rawhide? Some improvements were made recently.

I haven't been running the 5.21 beta for long to know if it's been fixed, but I've experienced this bug on 5.20.5 a few times with a very similar message (well, similar enough that DrKonqi said my new bug report was a dupe of this and to subscribe to this issue, which I did).

Running nvidia-beta 460.32 [well, it's currently the same as "normal" nvidia] on ArchLinux with frameworks 5.77 & Qt 5.15 (.2 at the time of this message, not sure if it was the same back when I subscribed on the 8th).

Comment 5 Nate Graham 2021-02-09 14:37:07 UTC

That's good. Thanks for testing. Let's call it fixed for now. If it happens again, please report it to the Nvidia devs, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-unix-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.

Comment 6 Unknown 2021-02-10 01:26:36 UTC

Will do, although currently my desktop is out of action so it's not likely to happen anytime soon.
