Application: plasmashell (5.23.5)

Qt Version: 5.15.3
Frameworks Version: 5.90.0
Operating System: Linux 5.13.0-27-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I was using the Pc and I updated through Discover, and I kept using the PC normally, when I finished some works, I left and I kept the PC on for 6 hours. I used it normally when I came back for 4 hours and then I turned it off.

- Unusual behavior I noticed:
The screen started crashing looking like a broken tv screen when there's no signal, once I turned it on again, 3 hours later.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
