@Gunnar: I only first recognized the issue last week -- it's possible I had been affected by the issue for longer, but did not realize it. After reading the description in the linked mutter bug, it does sound like I'm very likely affected by the same bug.
Tonight, I'll try the downgrade for the mutter packages as well.
