Description mitz 2010-03-23 21:01:35 PDT 
To reproduce: go to a video page on Hulu.

ASSERTION FAILED: willBeComposited == needsToBeComposited(layer)
(WebCore/rendering/RenderLayerCompositor.cpp:604 void WebCore::RenderLayerCompositor::computeCompositingRequirements(WebCore::RenderLayer*, WTF::HashMap<WebCore::RenderLayer*, WebCore::IntRect, WTF::PtrHash<WebCore::RenderLayer*>, WTF::HashTraits<WebCore::RenderLayer*>, WTF::HashTraits<WebCore::IntRect> >*, WebCore::CompositingState&, bool&))

Also, <http://www.emanueleferonato.com/2010/03/25/flash-elasticity-prototype-as3-version/>.

If I comment out that assertion, I get a "!needsLayout()" one later.
Comment 2 Simon Fraser (smfr) 2010-03-26 16:53:58 PDT 
I need an isSelfPaintingLayer() check in there somewhere.
