Description Wian Potgieter 2019-10-16 06:09:37 UTC

Application: plasmashell (5.16.5)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.0.0-31-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:
I scrolled the mouse wheel on the task manager to scroll between windows (task manager set to windows on screen & display).  I also just got a crash while typing this when I clicked on "configure panel".  This also happens when I Alt+Tab through my windows.  There is usually a delay, then the window decorations & panels disappear and then they restart.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Created attachment 123264 [details]
New crash information added by DrKonqi

plasmashell (5.17.0) using Qt 5.13.1

- What I was doing when the application crashed:

I scrolled the mouse wheel over the Volume icon on the system tray. 

Plasma then crashed and I had to restat it by executing "plasmashell --replace" via the run dialog

-- Backtrace (Reduced):
