Hello. I'm not native English speaker so sorry for all of my spelling mistakes. Month ago, I changed my GPU from R9 270 to RX 580. When I changed it, I formatted Windows, went to newer version than before (1809), installed all needed drivers etc. When I launched the game (CSGO), I noticed that screen has some weird issues, and they happened on every resolution another than 1920x1080. Screens of these issues: https://imgur.com/a/IkJCL2q https://imgur.com/a/YQW07IW For example, around the green crosshair, there is weird 'outline', 'shadow'. And it happens on every resolution another than native, 1920. From normal view, like where I seat, screen looks like a little bit too-contrasted/too sharpened, I can't describe this that easy. This happens on every driver newer than 18.3.4. The newest one, that went live 1 day ago, 18.10.2, has this problem as well. On drivers before and 18.3.4, everything seems good, seems because there on 1680x1050 I seen that issue with text (1st image, how it should look, 2nd image, how is it right now on these drivers): https://imgur.com/a/XqxjTDu Except this problem on this specific res (1680x1050), everything seems to be good. I think. Fun fact: I don't have this text issues on drivers newer than 18.3.4. What did I try? - Clean reinstall with DDU - New Windows - I think I installed every needed C++ Libraries and frameworks .NET - Card is brand new, but I still cleaned PCI-E slot etc. Card has like 1 month. - I tried RadeonMod, didn't work - I tried different MSAA and FXAA settings, they don't change anything from my issues - I tried Windows display calibration etc. Some facts that might have help you to help me (I beg you, please!): - One time, I uninstalled 18.10.2. drivers. Then I started instalation of 18.3.4. While AMD display driver was installing and display was blinking, for 2-3 seconds I've seen artifacts - black screen with pixels on. Then screen went black again, and Windows poped up blue screen with VIDEO_TDR_FAILURE and origin of problem: atikmpag.sys. It happened to me only 1 time. - When I was installing different drivers sometimes (it was pretty random) I was getting artifacts as well, black screen with colorful pixels on it, it was always only while AMD Display driver instalation. I remember, when I did format after changing old GPU, it happened as well, Windows was full clean and it still happened. - I got like 2-3 times these artifacts: https://imgur.com/a/K6AI5R3 They happened to me only while browsing internet, and when I for example scrolled down, they dissapeared. When I went back to the top of site, they appeared. They never shown up in a game or something. - I don't have atikmpag.sys file in Windows/system32/drivers. I have no idea why, I never touched anything there. I share you summary log from HWiNFO taken with 18.3.4 drivers: https://www.dropbox.com/s/5ec1rqqcafsyj74/log-summary.LOG?dl=0 I think thats all. Its a long post, but I'm trying to fix it for month. I'm so upset and sad, because I can't play CS with fun.
