They just needed baselines: http://trac.webkit.org/changeset/100557

These tests are still failing: compositing/geometry/video-opacity-overlay.html compositing/geometry/video-fixed-scrolling.html compositing/overflow/overflow-compositing-descendant.html compositing/self-painting-layers.html compositing/overflow/scroll-ancestor-update.html compositing/geometry/clipped-video-controller.html Were the baselines wrong?

'598 just added expectations, not baselines. It looks like some of these (at least compositing/geometry/video-opacity-overlay.html) are in fact rendering correctly but need a rebaseline. They've been somewhat unstable lately because of recent configuration changes which changed the tests from using the software video path to using H/W colorspace conversion and scaling, which very slightly changes the video's display.

As far as I can tell, they all seem to just need a rebaseline. Steve/James, can you please verify that and submit new baselines? Thanks!

I filed the bug as WebKit gardener - leaving to James to confirm as I think he's the owner of these tests.
