On Mac, load up LayoutTests/compositing/geometry/video-opacity-overlay.html and reload the page a few times with Command-R. Every once in a while, the video is blank. I think this is a recent regression.

There are some pretty obvious differences in the movie notifications we get from QTKit in the success and failure cases. By adding some printfs, I saw: Good loadStateChanged (delayed 1) loadStateChanged (delayed 0) updateStates: network state 2, ready state 2 setUpVideoRendering currentMode=0 preferredMode=3 acceleratedRenderingStateChanged setUpVideoRendering currentMode=3 preferredMode=3 seeking to 0.000000 (metadata available 1) timeChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 Bad loadStateChanged (delayed 1) loadStateChanged (delayed 1) loadStateChanged (delayed 0) updateStates: network state 2, ready state 2 setUpVideoRendering currentMode=0 preferredMode=3 acceleratedRenderingStateChanged setUpVideoRendering currentMode=3 preferredMode=3 seeking to 0.000000 (metadata available 1) timeChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 rateChanged (delayed 0) updateStates: network state 3, ready state 4 rateChanged (delayed 0) updateStates: network state 3, ready state 4 rateChanged (delayed 0) updateStates: network state 3, ready state 4 rateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4 loadStateChanged (delayed 0) updateStates: network state 3, ready state 4
