Hello Silvério,
Reading symbols from /usr/bin/kwin_wayland... (No debugging symbols found in /usr/bin/kwin_wayland) BFD: warning: /tmp/user/1000/coredump-ySV5m6 is truncated: expected core file size >= 2365169664, found: 2147483648
it looks like for some reason the kwin_wayland exceeds the address space limit of systemd-coredump, therefore the results are not good. If you want to give it another try, then please uncomment and raise this limit from e.g. 2GB to 3GB like this: /etc/systemd/coredump.conf ... ProcessSizeMax=3G ExternalSizeMax=3G ... systemctl daemon-reload Then the size warning hopefully goes away on the next attempt, and a better backtrace might be printed. Kind regards, Bernhard
