Hi, To add further information - issue seems to be pipewire. Searching my records the following applies : 2023 01 26 Update - pipewire 0.3.63-1.fc36 - no crash issues and same for all fc36 updates. 2023 05 15 Upgraded to F37 - pipewire 0.3.70-1 no issues. 2023 06 03 Update - pipewire 0.3.71-2 - 1 instance of a crash. 2023 07 26 Update - pipewire 0.3.75-2 - 3 instance of a crash. 2023 07 30 Update - pipewire 0.3.76-1 - 4 instance of a crash. Unsure if it is a stability issue between pipewire and wayland, and whether it exists between pipewire and x11. Pipewire 0.3.70-1 may have an issue as only 19 days between that version and then ext which had 1 crash for kwin. Regards, Shadders.
