Here's gif of it appearing even in discord.
In this situation I had game in background, where it also appears, but in discord it appeared on various places (got longer vids) and even without game in bg. I had it at repair shop, they said its fine, tested, all good. I went there ran game and it appeared lol. Then it refused to appear anymore but at least they saw it one time. Offered to send to distributor in country but i didnt want to be too long without gpu and wanted to gather more proof because im pretty sure those guys would say its fine as well. Now im bringing my old 1070 nvidia and gonna test with it in the system, if it all works fine just like with integrated card im gonna insist on new one and get lawyer if needed involved. Also gonna try switching psu cables first but doubt its that. Its really weird though, all the stress tests passed with flying colors, no artifacts or anything anywhere except in games at specific times or locations. Like in kingdom come it just appears in cutscenes(ingame ones not video) and on black bars on top and bottom.... In the shop they ran furmark for 10 min at rage mode(overclocked) and it was super stable, temp fine...
Here's an update with everything I've tried before and recently, in no particular order. If anyone has any idea what else to try let me know. I plan to keep trying new games until I find enough where it happens consistently and then I can send it back because all the stress and benchmarks are fine.
Tried integrated GPU and older GPU card I have (nvidia 1070) no artifacts
Tried HDMI 2.1 from PS5
Tried two different dpi cables and 2 HDMI cables
Tried 3 different monitors(or well 2 plus tv)
Installed fresh win11 without anything and tried there
Freshly installed various drivers
Underclocked
Overclocked
Tried all the stress tests and benchmarks I could find
I even recorded in-game footage and it shows these artifacts in the video
Tried different resolutions in-game and in Windows settings
Tried different refresh rates
Fixed card sagging
Expo (for RAM) is disabled in bios
I don't have another PCIe port to test, or I do but gpu can't fit there
Removed drivers through DDU between testings
No remaining PCIE cables from the PSU but no place to plug it in in PSU even if I had it
I switched cables around a bit inside between things
It might have worked in the end when I tried running it without any drivers but the game was so choppy and lagging I couldn't test more times and CPU was maxing so maybe it was running off it.
Installed the driver only from March 2023, for a moment I thought it worked but after a restart same old, not to say the restart made it worse it's just that it's not consistent.
I reinstalled the newest drivers
Overlock and underclock didn't help from either afterburner or amd software, same with some gaming profile t hat does things.
Can't run memory clock under 2500
As for the games, I haven't really been playing much but I did notice it originally in Honkai Star Rail, which is a mobile game and I thought oh it's flashy and unpolished maybe it's just the game and it wasn't much and at random places.
Later, ESO - older mmo it would show up a lot and in all different colours and places.
Wanted to play two mirror but noticed it right away in the menu, noticed it in the game too but it's a bit more discreet there.
Started playing kingdom come deliverence and it only shows in certain cutscenees and just in a black spot above the cutscene though I think it went down a few times as well.
I noticed it in discord as well but this might just be down to hardware acceleration there.
Warframe I just ran once to test and I could see it popping up here and there when paying attention to it.
Oh and this is how the card is powered, it's not dusty or dirty the camera just went into night mode and messed up the colors.
