Application: kwin_x11 (5.24.5)

Qt Version: 5.15.2
Frameworks Version: 5.94.0
Operating System: Linux 5.3.18-150300.59.68-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.3"
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
After leaving the screensaver, the 2nd Screen was not any longer recognized. I turn it off and on and set the Unify outputs again.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
