Bug 429990

Application: kdeconnectd (1.4.0)

Qt Version: 5.15.2
Frameworks Version: 5.76.0
Operating System: Linux 5.6.19-159.current x86_64
Windowing system: X11
Distribution: Solus 4.1 Fortitude

-- Information about the crash:
- What I was doing when the application crashed:
Just booted the device

- Unusual behavior I noticed:
Plasmashell didn't load properly, 1 have 3 screens and often the (primary) middle screen is black (but shows panel and panel is accesible) and I can't right click on it.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault
