Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic

SUMMARY
KWin_wayland segfaults when any monitor is disconnected, such as when my LG
24UD58-B goes into DPMS power save mode when the screen saver activates. It
reconnects itself when DPMS re-powered.
STEPS TO REPRODUCE
1. Log into Plasma Wayland session.
2. Lock the screen and wait for the screen saver to power the monitors off.
3. Wake the desktop and unlock the screen.
OBSERVED RESULT
Kwin crashes, and the session is restored from scratch.
EXPECTED RESULT
The session continues unabated.
