It is a crash but also Xorg tries to catch its own crashes which creates this headache for maintainers whereby you often lose all trace of where it crashed. Often but not always, so we do get plenty of proper crash reports from Xorg. In my experience it just takes more attempts and eventually one will leave a file in /var/crash/

I posted a bugreported here https://gitlab.freedesktop.org/xorg/xserver/-/issues/1197 with configu details. But it seems to be nvidia, but may be a workaround is possible in Ubuntu? This bug prevents me to use Linux for daily docking /undocking cycles for HomeOffice (works fine with Windows).
