Description Tobias 2025-09-11 10:31:16 UTC 
Application: kwin_wayland (6.4.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.17.0
Operating System: Linux 6.15.9-201.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42.20250819.0 (Kinoite)"
DrKonqi: 6.4.4 [CoredumpBackend]

-- Information about the crash:
Regularly when waking my Laptop from sleep (often, as in this case, automatic sleep triggered by inactivity), Kwin crashes on wakeup, resulting in all applications being terminated.

The two notable modifications to my system are some kmod based kernel modules that I need to support my hardware and that I'm running the KWin script Krohnkite.

I selected "Fedora RPMs" as Distribution method, but that's only half correct, since I'm running Fedora Kinoite. Here's the output of rpm-ostree status:

Comment 3 TraceyC 2025-09-16 00:54:46 UTC 
Thank you for the bug report. Based on the backtrace this looks like a duplicate of bug 504959. This was fixed in Plasma version 6.4.5. The fix will reach your system when it updates to that version.
