Description Circle 2020-11-18 08:35:56 UTC

Application: plasmashell (5.19.5)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.8-200.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: "Fedora release 33 (Thirty Three)"

-- Information about the crash:
- What I was doing when the application crashed:
Right clicking tasks in the task bar to close the application or to perfom a certain action causes Plasma to crash on many occasions. 

- Unusual behavior I noticed:
There seem to be a conflict of focus. In my Fedora 32 installation, by hovering the mouse over a certain task, you get a miniature preview of the actual window of given task. When right clicking the task, the preview is dismissed and a set of actions are presented in a meny. On my new Fedora 33 installation, there is a conflict in this. When right clicking the task, the preview is still in focus, not dismissed. The menu sometimes end up behind the preview and sometimes in front, however the preview is not dismissed. Right clicking the task many times does not help and causes Plasma to crash on many occasions.

The above is also the case for System Tray. I alsmost pulled my hair to disable the Plasma browser integration tip which is usually dismissed by right clicking it. This was not possible as the title was in focus instead of the menu option where one is able to dismiss it.

There is a lot of crashes in general in Plasma. The crash report tool crashed, causing a storm of crashes of it, resulting in my desktop being filled with crash messages.

The crash can be reproduced sometimes.

-- Backtrace:

It appears to be crashing in the Intel iGPU driver.  You'll want to report this to the mesa developers. See https://docs.mesa3d.org/bugs.html
