This is just a downstream bug from https://bugs.kde.org/show_bug.cgi?id=509004 A fix has already been issued here: https://src.fedoraproject.org/rpms/kwin/c/7525f9657c8b6fdd425cfd8dd9b7f04713164a24?branch=rawhide Reproducible: Always Steps to Reproduce: (copy&paste from upstream bug) Lenovo T14s Gen 2 laptop. I have two similar monitor setups at home & work. Both are 2x 2560x1440 monitors connected via USB-C -> left monitor -> MST/DP Out -> right monitor. The crash is reproducible in both setups. Every time I unplug the USB-C cable to the external monitors, after a few seconds kwin_wayland crashes, taking most of the desktop applications with it (Firefox, Thunderbird, VSCode). The only windows that survive the crash are Konsole, Dolphin & LibreOffice (I'm using the kf6 integration for it). The problem started after I upgraded to Plasma 6.4.4. I have already verified that it is not related to the kernel 6.15.x -> 6.16.x upgrade in Fedora. The crash also happens under 6.15.x, where Plasma & external monitor setup was working fine before the upgrade to 6.4.4. I have another laptop at home that is connected via HDMI & AVR to a TV. I have not observed the crash in that setup. The crash can be reproduced every time. Actual Results: Kwin crash Expected Results: No crash :-)

Proposed as a Freeze Exception for 43-beta by Fedora user marcdeop using the blocker tracking app because: A kwin bug causes a severe crash on a fairly common situation: unplug a monitor from the system. I request an update to be allowed to proceed :-)
