You are **very** wrong. This is YCbCr 101: 420 has all the same colors as
444 does. Just if one pixel is fixated the entagled pixels have less than
all possible colors. This is also not corners issues, it is reproducable on
one color all over the plane.

Then do reproduce with that and attach the sample having the same metadata (colorspace/primaries/transfer) to the ticket, with mpv and ffplay screenshots with the rendered output.

I am asking this, because based on the tests I have made I still believe there is no color space issue, but feel free to prove me wrong.

Thanks,
