Bug 510917

Application: kwin_wayland (6.5.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.2
Frameworks Version: 6.19.0
Operating System: Linux 6.17.1-300.fc43.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 43 (KDE Plasma Desktop Edition)"
DrKonqi: 6.5.0 [CoredumpBackend]

-- Information about the crash:
To be completely honest, all I did was walk away from the computer for a bit, and when I came back, I got a message from drkonqi that kwin crashed. My computer did go on standby (The screen turned off).

Also note: this is on 6.5.0 using a build on copr, not on official repositories. But the spec files (aka the "recipe" for building the packages) are the same as what they will be in final.

The reporter is unsure if this crash is reproducible.
