Public bug reported: I don't know what causes it but frequently I see my journalctl being spammed with gnome-shell errors (see attached journalctl snippet). If I do nothing about it, then within a few hours gnome-shell is slow and may eventually freeze. So I end up rebooting to reset the system and avoid a freeze.
I'll keep my eye out for reproducers but in the mean time I wanted to record this somewhere in case others see it. This happens every couple of days on both my laptop and workstation and both systems are running 19.10.
