This test case has a high fuzzy threshold.

If I remove this line, both UseSkiaForComposition on and off, actual results show the first frame.
This test case expects the last frame.
This bug is not a regression of UseSkiaForComposition. I think this is a GStreamer backend bug.

I don't see any failure on https://results.webkit.org/?suite=layout-tests&test=media%2Fmedia-vp8-hiddenframes.html&platform=GTK&platform=WPE ?

[Fujii Hironori]

Needs to "export WEBKIT_USE_SKIA_FOR_COMPOSITION=1" or removing the fuzzy meta element at the moment.

There are two problem.

1. the first frame is painted even though the last frame is expected
2. Looks a bit darker if Skia compositor is enabled

I think this bug ticket should track the #1 problem because that's the main purpose of the test case.
