I am having these issues just start. I've had this GPU and setup for 3 years now and the problems just started last week. These artifacts just start showing up under minumal loads, just browsing Firefox, Windows menus, Radeon Software etc.
When I do start Warzone it crashes when loading the main menu.
I've tried using the DDU tool and installing the latest drivers and doing the same for the earliest available driver on the support page for the RX 580 multiple times. I'm at a loss worried the GPU is going bad. Any other suggestions?
