^ The video is private. However this might be a dupe of bug 1259735. If you run into this, try rotating the phone and see if that fixes it. If so it's probably a dupe.

Thanks. Yeah, it does look a lot like bug 1259735. Opening the URL bar and going back will trigger a full layout/repaint which fixes the problem, same as an orientation change would. I'm going to close it as a dupe but we should verify this once that patch is uplifted.
