So far the transition to Android 12 has gone smoothly. The display's Minimum Width got reset to 384 dpi, but I switched in back (in Developer Options) to my previous setting of 720.
I did encounter the new adaptive-refresh behavior others have reported, but I'm not sure it's even a bug, or if it is, there's an easy workaround. I turned on Show Refresh Rate (in Developer Options) and confirmed that in many apps, as reported, if I flick my finger briefly to initiate a scrolling action, the refresh goes up to 120 Hz while my finger is touching the screen, but immediately drops to 60 Hz when my finger moves away. However, if I keep my finger on the screen and in motion for more than half a second before moving it away, the scrolling continues smoothly at 120 Hz. For me, that's a better workaround than forcing the refresh to stay at only 60 Hz and abandoning smoothness, or only at 120 Hz and draining the battery unnecessarily.
