Ok it wasn't clear to me if the fault was gnome-shell or xwayland. Following the instructional link, I do see https://errors.ubuntu.com/user/ID items, but none around this time. The workaround in bug 994921 is outdated and the line it says to comment is no longer in the file... so I'll just see if it happens again.
