TPM has a lot of visual oddities, one glaring one for me is the initial shot of the jedi temple, the surrounding areas look really flat and not at all like they appear in AOTC and ROTS.
Also, in AOTC, on the initial shot of Kamino, the water looks really fake and not convincing at all.
As for frame-by-frame specifically, I honestly hadn't noticed that. I bet there's a ton of those oddities though.
