Clearing icon and thumbnail cache help? Icons go black when hovering over them

How does one clear their icon and thumbnail cache so the icons don't go black when you hover over them with your mouse?

Appreciate it 🙏🏼

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.
