Recently went from an RX 470 to RX 580 uninstalled drivers from AMDs tool, caused strange artifacts randomly; thought the new card was dying. Couldnt be the case brand new Nitro rx 580; Drivers were fault, tried 18.12.3 worked okay for a short bit but began again.
I believe the 19.2.2 driver need to be installed on a purged driver baseline using DDU to prevent issues downgrading aswell.
Used DDU twice to purge all AMD drivers
Reinstalled 19.2.2 - Issues seem fixed!
RX 580 - 61c @100%load and 1500 rpm fan.
