Hard drive icon flickers from custom icon to folder icon
This question may have already been answered, but I tried several phrasings in my searches and could not find anything similar. So here's the problem: I have a backup drive with a custom icon. At random times, roughly ten times an hour, Monterey redraws the icon for the backup drive as a simple folder, then changes its mind and redraws the custom icon correctly. I wouldn't mind the bug but for the fact that the activity is as distracting as one of those infuriating web advertisements that flashes something on and off.
Has anybody experienced the same problem? It does appear related to the many problems reported about external hard drives. The only solution I have come up with so far involves a large sledge hammer.
