I've looking for an answer in forums for two weeks without success.
I've bought a Sapphire Radeon RX 480 Nitro 4G a week ago. I play exclusively World of Warcraft and it runs fine but when I play for more than two hours and ALT+TAB to my desktop, it has changed colors. Every red color goes to blue on icons, desktop, windows etc ... it seems as the RGB colors have been altered and it's not due to a Windows Theme change. As I say it happens when I spend long time playing. If I switch to my desktop one hour after start playing everything is OK. BTW I don't seen any flickering of faults during gaming. It runs on almost max details. Any clue, please?
