Public bug reported:

Not running X, but apport doesn't have other Display bug options. 
Since upgrading to Ubuntu 26.04 the Display (running Wayland) seems to freeze 
at random times and in random applications.  This requires a hard reboot.
Happens several time a day.

I cannot figure out what might be the cause.  I haven't found other
similar reports that are recent.
