I just upgraded to Ubuntu 18.04 with libmutter 3.28.0-2 and ran into this; monitor poweroff/poweron yields a crash of gnome-shell. The good news is that the applications are not killed like they were in 17.10 (with wayland?). But waiting for the ubuntu-bug crash file to get generated isn't a good use of my time either.

For me, applying the following patch works:

Patched binaries are here:
