Square flashing artifacts in menu UI

In any menu, most notably present in challenges section there are flashing square artifacts, I've had this issue even during beta, these artifacts are only present on the UI, not on the gameplay HUD or actual game, it's like the menu overlay is glitching out.

First I've thought that this could be a GPU issue, but I have never had this happen in any other game, only this one. Tested on multiple driver versions, result is always the same.

Video and screenshot with artifacts included, this one is from the beta but it is the same bug, here's an example of battle results screen.

My GPU is Radeon 7900 XTX
