From the time that the failures started, it looks like this is due to http://trac.webkit.org/changeset/100360, perhaps due to unexpected fallback paths for expected results?</thetext>

    <thetext>&apos;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&apos;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&apos;s display.</thetext>

    <thetext>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!</thetext>
