New renderering quirk in youtube: different colour (grading) in the left and right halves of the image, split right down the middle.

I've been spotting this over the last couple of days in video's of different makers. Took a screenshot from this video: https://www.youtube.com/watch?v=anH5KkuKets

It looks like it happens when there is a big difference in movement on the two halves of the screen. The example is from Firefox, but Chromium (both on the most recent versions) has the same issue. So probably something something codec pacs or GPU drivers? (Fedora 44, with most recent updates on a Ryzen AI 300 series)

A screenshot of a video. It shows a road with sidewalk. There is a noticable colour difference, where the right half of the video looks darker than the left. With a strong divider down the middle.

If I download the video and play it in the default Fedora video player it seems to even get worse and the screen is split in not two but 4 columns with differences in colour rendering. (screenshot below).

Playing the same file in VLC and and the issue doesn't show at all. There the entire frame has the same colour rendering.

A frame of video showing a intersection. The frame seems to have four equally sized vertical columns with slightly different colour rendering each.

@Dany dunno if useful data point, but I just watched that same video via a Chromecast, and had no issues with the colour.
