In the previous bug report, I talked about basically the same problem, but I discovered some new information about the bug. I couldn't edit the previous bug report so I created another one that will help a lot. When I put it in first person, the camera freezes and duplicates the hand several times, in TAAU upscaling mode this doesn't happen, only in bilinear. Watch the video to understand better.
You should be able to edit your previous report by clicking on the "Edit Report" button on the right.
