Graphical artifacts only on Linux

[Pawys]

I recently upgraded my Gigabyte RX 580 to a Sapphire Nitro RX 6700XT .

 

When i first got the card i did some tests with some of my games and everything worked fine. When i launched the new spider-man however i got an driver issue (the game itself may have been the issue since i was using a cracked version at the time). That prompted me to change mesa to mesa-git to check if that would fix the driver problem. It did not.

 

But after doing that some small green boxes started appearing on the lutris client. (The boxes only appear sometimes and are quite easy to miss so its entirely possible they did appear before installing the mesa-git driver and i just didn't notice it). The boxes disappear when the window is not active.I saw that the somebody else had the exact same issue but he didnt have any artifacts in games.I didn't think much of it since the only application it affected was lutris and i thought that it strictly was a lutris/mesa-git issue. But since i didn't think i needed mesa-git i once again changed it this time to the normal mesa driver. Which did not change the lutris issue but i still ignored it.

 

A couple of days later when i launched cs go and went to the in-game menu (as shown on the gif it only happens in the menu) it happened again. This time it were black boxes sometimes changing colors. I thought it had to be a hardware issue and that i just had a faulty GPU.But i checked cs go on windows and i did not have such issue. I also got some small artifacts while playing hitman 3 only in the weapon selection screen

 

 

What i tried already:

Changing mesa to mesa-git

Changing my kernel from Linux-zen to Linux

Trying a different Linux distro (pop OS)

Changing my GPU bios (My graphics card has 2 bioses)

None of it fixed the issue.

I have been using windows for 2 weeks so far playing different games and i didn't experience any issues.
Should i return the card? What could be causing this?

 

Edit: I saw that some people had almost the exact same issue as me but doing what they did didn't fix the issue
