Another gdb run
> The Wayland connection broke. Did the Wayland compositor die? Seems like it's actually KWin that crashed. Can you get a backtrace of the KWin crash? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl Created attachment 140537 [details]
coredumpctl gdb kwin_wayland
This is my gdb output for the coredump of /usr/bin/kwin_wayland.
I hope this helps. If you have any more questions or need more info, just ask.

backtrace sddm-greeter
I don't know if this is related but I found another corefile for the sddm-greeter after running coredumpctl as root.
I have attached the corresponding backtrace.
#0 0x00007f503871a110 in ?? () from /usr/lib/pipewire-0.3/libpipewire-module-protocol-native.so It seems like kwin crashes in pipewire code? Created attachment 141237 [details]
gdb plasmashell crash
I can replicate this issue. I don't have a second screen to detach the tab to, but just dragging a tab to the desktop to detach triggers the same result. This only happens on Wayland, detaching works as intended on X11.
I've attached a gdb run of plasmashell, I don't get an entry in coredumpctl.
Probably unrelated, but I also get the following just by dragging anything (tabs, text, images) around for a couple of seconds on Firefox. Firefox exits afterwards:
Gdk-Message: 18:48:18.315: Lost connection to Wayland compositor.
