Stuttering on some files, not others

Not sure how long this has been going on b/c hadn’t used the 4k+ for a bit, but just noticed that on some files there is stuttering and on others there isn’t.

Not sure how else to describe this. I’ve posted some logs here of a stuttering video.

Let me know if you have any questions. Thank you.
