Some video previews/thumbnails do not update while the video is playing STR: 1) Load a video at cnn.com (http://www.cnn.com/video/#) 2) Load a video at youtube.com (http://www.youtube.com/watch?v=OzvhSZzRqYg&feature=rec-fresh+div-r-1-HM) 3) Switch focus to another app 3) Hover over the firefox taskbar icon and notice how the video on cnn is still shown as playing in the thumbnail and the youtube video is not. Hover over the previews and the same results. Both use flash.

I thought this was an OOPP bug at first so I was checking with the guys in #content. jimm said, "the code we use to render the thumbnails will need to copy the buffer from the window in the child somehow." Not sure if that helps you out Rob.

URL from comment 0 step 1 worked, but URL from step 2 still didn't work. Looks like its a difference between windowed which doesn't work, and windowless which works; using testcase from bug 547142 https://bugzilla.mozilla.org/attachment.cgi?id=427782 Windowed only gets a snapshot when opening the preview panel, while windowless gets live updating. Testing using latest hourly Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.3a2pre) Gecko/20100222 Minefield/3.7a2pre (.NET CLR 3.5.30729) ID:20100222175309

Does this bug depend on Core bug 313462? See bug 313462 comment 45.

Indeed it does.
