Can you try different decoders? E.g. try LAV Video Decoder. Both software decoding and DXVA.

Fixed after I reset PotPlayer settings to default and chose MadVR again. I didn't try reset PotPlayer before to avoid losing key bindings and other settings and thought PotPlayer might not be the issue.

The default settings for MadVR don't look as good as Windows "Films and Movies" player on a few 4k videos I am testing, but I will try other settings to figure that out. Thanks for the quick response.
