Able to bisect this failure to r274264. Able to reproduce on r274264 but unable to reproduce on r274263 or r274258, using this command: run-webkit-tests compositing/visibility/iframe-visibility-hidden.html --iterations 1000 -f -1

This change was all in media code, so a little surprising. But if it's indeed that, it has to be a substantial issue. I think.

Not really surprising; the test case uses video.

Test is a image failure, not a timeout; video is accurately firing the 'load' event. If the background isn't painting, that's not a video bug.
