  Target Milestone: ---

Application: kwin_wayland (6.7.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.11.1

-- Information about the crash:
Before logging out, I manually closed all active applications, then refreshed
the system and logged out (without restarting).

When I logged back in, plasma-drkonki reported that KWin had crashed
unexpectedly.

The reporter is unsure if this crash is reproducible.
