Question Artefacts on steam overlay

Feb 5, 2022
Hey guys, I just got my new pc that has a RTX 3060 Ti, and I updated my drivers, got Steam and one game, however, I started noticing some artefacts, and I can recreate them on Steam Store, they look like this:

Is it a problem with the GPU? What could I do?

I tried switching monitor cables from DP to HDMI and on HDMI there are less artefacts, but they are still there. Unfortunately, I have no second monitor to test it out. I'm trying to reinstall windows at the moment. Any suggestions? Thanks a lot!
