Description of Original Problem: I've had these flickering squares since I got the card nearly a year ago. It would only happen on very specific textures and it never bothered me in game, but it recently happened here in Hitman 2 (focus on the gold key with a brown background) and I'm getting scared if my card is failing. This also happens on Rainbow Six Siege only on weapons textures next to the guns when you're picking a character. It also happened in Warframe on color pallettes but it wasn't nearly as frequent as Hitman 2 and R6S.
Troubleshooting: I've undervolted, reset to default settings, tried all presets in the Radeon software, turned off all background programs, turned off/down all graphical settings in game, tested on both my monitors, but nothing seems to fix it.
I've stress tested this card with several different softwares and it never showed any signs of failure. I've also tested it in OCCT with error checking mode on and it gave me 0 errors. I've searched everywhere for this specific issue but nothing seems to come close to this.
Any help or guidance on what else I can try would be really appreciated.
