Description Alejandro Aibar 2020-02-01 00:13:26 UTC

Application: plasmashell (5.16.5)
 (Compiled from sources)
Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-29-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed: I was trying to open the KDE dash.

- Unusual behavior I noticed: Every window in the session was covered by some black strange lines. Also, it was randomly closing those windows.

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

New crash information added by DrKonqi

plasmashell (5.18.0) using Qt 5.12.4

- What I was doing when the application crashed:


- Unusual behavior I noticed: Every window in the session was covered by some black strange lines. Also, it was randomly closing those windows.

-- Backtrace (Reduced):
