mutter is broken on gnome os in Boxes
This only broke on the default setup in Boxes, it works fine or my laptop.
Bisected this down to 27f798b6
27f798b6d014fa6f336dd4ceb1fcf6d587b44594 is the first bad commit
I can provide a better stacktrace and stuff but it will take a while since it's only reproducible in a vm, so let me know ahead of time if possible!
