Pixel Artifacts

Hey Everyone,

I just got started ripping blu rays and am running into an issue. Standard blu rays rip/play fine with MakeMKV/VLC, but when I do the same with 4K blu rays, I get these white/blue/red pixels that jump all over the screen (see the video). This occurs on all 4K discs, and standard blu rays play/rip perfectly.

Has anyone seen this before? I also replaced the original cable with a new USB 3.0 type B cable which I thought might help the issue, unfortunately it hasn't. It's also not an issue with the discs/films themselves, these errors only occur on my PC and not when playing them on a PS5/4K TV.

For reference, I'm using:
