It's possible that this is related to the Mutter fix from last week which manifests itself via changes to the launcher. However, this should have been fixed on Friday. Can you add some steps to reproduce?

Had a few desktop shell lockups. Pattern seems to be when running snap refresh, but this time happened when running snapcraft --use-lxd. Feels like something related to mounting / unmounting devices. Got this from the journal.
