Yep. Tried Safe Mode. The problem doesn't seem to happen there.

I finally installed AMD's old, Recommended graphics drivers (version 22.5.1 from way back in late April 2022). That's replacing their latest drivers (version 22.11.2). The problem doesn't seem to happen with these old drivers either. So, it looks like the problem is caused by AMDs GPU drivers (or their associated Adrenalin software) from sometime after that. And, since the problem doesn't seem to happen with the October 2022 drivers installed with Windows by default, I'd say it happened sometime after October.

I guess I'll continue using their old GPU drivers (at least until I run across a game that has issues with them).
