Well it's a relieve for me tbh, thanks guys!.
I wouldn't be so quick to assume that. I've not heard of anyone else exhibiting those artifacts (yes folks those are artifacts, they can be hardware or software or firmware caused) you are seeing on screen. I play this game quite a bit and it has its issues, but that, is not one of them.
Have you changed any settings in the Nvidia Control Panel?
A hint here might be that you are apparently only seeing this at 4K. Is that accurate or do you see it at all resolutions? How are you connected to your display? What type of display do you have?
