The test imported/w3c/web-platform-tests/media-source/mediasource-video-is-visible.html has started failing as of r284368. The test does some XHR requests to get a video file that just shows a static blue rectangle, but after the revision in question, the expected blue square is not visible anymore.

Sadly this test still fails. The video is visible now, there is a blue square as expected but the actual blue square is the color #0100ff and what the test wants is #0000ff. So close.
It was passing when I submitted the patch but I haven't checked since then. Maybe some of the recent changes around colorspace handling broke it again. Please open a new bug or rebaseline accordingly :)
Reverting r287323 gets me a blu^Wgreen test again, fwiw. Maybe this should be flagged as a fuzzy test.
r260879 (2023-02-27) was the last build in the bots where this passed in GTK. It has been failing in Release since, while mostly passing in Debug.

Wrong revision due to repo changes... Anyway. I've noticed this is a problem with more tests. It seems that the test runner fails to capture video image in the GStreamer ports: imported/w3c/web-platform-tests/media-source/mediasource-video-is-visible.html media/media-source/media-source-video-renders.html media/track/track-webvtt-no-snap-to-lines-overlap.html media/track/track-webvtt-snap-to-lines-inline-style.html media/track/track-webvtt-snap-to-lines-left-right.html media/video-with-alpha.html
