Bug 452001

Application: plasmashell (5.24.3)

Qt Version: 5.15.2
Frameworks Version: 5.92.0
Operating System: Linux 5.16.15-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.24.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Nothing. Was checking something on my phone.

- Unusual behavior I noticed:
Panel and icons disappeared from primary monitor, but wallpaper remained. Wallpaper disappeared from secondary and tertiary monitors, leaving just black screens with windows. All reappeared a few seconds later.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
