Description Jose Quintana 2020-03-23 23:27:47 UTC

Application: plasmashell (5.18.3)

Qt Version: 5.14.1
Frameworks Version: 5.68.0
Operating System: Linux 5.5.10-arch1-1 x86_64
Windowing system: X11
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:
I was clicking on notification icon on bottom-right, then the notification panel was transparent completely, few seconds later the entire screen was transparent, and finally  was crashed.
After that, the desktop manager was reseted automatically and worked as usual.

- Unusual behavior I noticed:

The first time that I have faced that issue.

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