Public bug reported:
Using ubuntu wayland with dual monitors, configured above each other.
Dock is configured at both displays, not hiding.
Icons for "terminal" and "libreofffice Writer" are present at the dock.
Start terminal on primary screen by mouseclick on dock.
Start libreoffice Writer on primary screen by mouseclick on dock.
Terminate libreoffice Witer by mouseclick on X.
Repeat the starting and stopping of Writer.
Login-screen will appear. Syslog shows:

failed: Resource deadlock avoided
Oct 15 00:09:51 Gert2 gnome-terminal-[6439]: Error reading events from display:
Connection reset by peer
Oct 15 00:09:51 Gert2 systemd[5755]: gnome-terminal-server.service: Main
process exited, code=exited, status=1/FAILURE
This problem doesnot occur in a dual monitor-session without wayland.
It also doesnot occur, if only one monitor used with wayland
It also doesnot occur, if the dock is only present at the primary screen.
It also doesnot occur if second started application is present at the dock and
doesnot add an icon to the dock (as libreoffice does).
All other dual monitor/dock configurations seem to have this problem.
No idea if this is helpful info, but the used graphics card does not support
