Comment 13 for bug 1897224

I had a go at fixing this in https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1508 -- taking the patches from that MR and applying them to the Groovy mutter source package gave me a Wayland session that supported X11 snaps again.

It is probably worth waiting for a review from upstream before going further. I've done the testing they asked for with the "autostart-xwayland" feature enabled, so hopefully that will come soon.
