Fwiw, this happens every time I turn off the only monitor attached to the computer, and it loses all unsaved data, so for me it's critical - I can't use gnome-shell on that computer.

By the way, upstream appears to have a fix for this too: https://gitlab.gnome.org/GNOME/mutter/commit/71b4ef5940d16f7d3cb7dca5c224784315803492

Launchpad bug 1724439 already covers that.

It would be a bonus if this bug was resolved by the same fix so we'll wait and see.

Looks like this was fixed in Gnome 3.28 ... let's see and this bug can auto-expire if so.
