@Noctua What you are describing does sound like some sort of chroma crosstalk. It seems it can have quite a few different variations, depending on the particular hardware.

I did some digging regarding different kinds of chroma crosstalk artifacts. Does any of these look familiar?
Pokémon Stadium title screen on PAL 64 S-Video (improper vs. proper circuit)
Chroma leaking into luma due to bad comb filter when digitizing VHS through composite
Diagonal + checkerboard-like artifacts in “S-Video” capture, due to feeding CVBS into luma
Mesh pattern and washed-out colors on SNES S-Video output
N64 S-Video chroma crosstalk artifacts, with focus on color saturation

You may want to expand the images to full size to properly see the artifacts (or lack thereof).
