3080 strix here. had some strange texture/model artefacts in csgo where the textures would extend/radiate and fill the whole screen and after exiting the game I had green artefacts/dots on my screen with chrome youtube open, but this was with older driver 456.71 and only happened once during 2 months and a restart fixed it. updated to 457.51 yesterday and ran a few tests (furmark rog edition, control, death stranding, quake 2 rtx) all fine. but noticed a small black square appearing for a brief second when ccleaner is open. this is strange, driver issue?
