Seems to have been random - no dump was generated. coredumpctl shows the below: Thu 2023-02-09 19:13:48 CET 1745 1000 1000 SIGABRT inaccessible /usr/bin/kwin_wayland - the journal is showing the below: Feb 09 19:14:06 arch-Bednar plasmashell[54631]: trying to show an empty dialog Feb 09 19:14:06 arch-Bednar plasmashell[54631]: file:///usr/share/plasma/plasmoids/org.kde.plasma.battery/contents/ui/CompactRepresentation.qml:61:17: Unable to assign [undefined] to int Feb 09 19:14:08 arch-Bednar plasmashell[54631]: org.kde.kf5.kwindowsystem.kwayland: Failed to recreate shadow for PlasmaQuick::Dialog(0x562495619b10, name="popupWindow") Operating System: Arch Linux KDE Plasma Version: 5.26.90 KDE Frameworks Version: 5.102.0 Qt Version: 5.15.8 Kernel Version: 6.1.10-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 6800 XT I am not sure if the titular Failed to recreate shadow for PlasmaQuick has anything to do with this. What I did notice though was that when kwin recovered, all windows and applications were killed and had to be restarted.
Created attachment 156107 [details] gdb dump apparently I needed root to access the file. attaching what I got
"Failed to recreate shadow for" can be printed for various reasons by plasmashell. If kwin crashes, we need a backtrace of the crash; otherwise the crash is inactionable.

Created attachment 157881 [details] gdb wayland kwin Reopening as this crash happened earlier today. This time thee was nothing about failing to recreate shadow for PlasmaQuick. I have a backtrace but it appears useless and I am noticing a strange pattern. Whenever this crash occurs, > $ coredumpctl list --reverse shows the backtrace of kwin_wayland is "inaccesible". Executing the above command with su privileges, I do get the attached. Any ideas?
It's missing symbols for the most relevant part. It mentions spa which could mean it's the known (and fixed) pipewire crash
