When fullscreen window lose focus, a fake title bar is painted
Steps to reproduce: 1. Make something in fullscreen (DOM fullscreen, not fullscreen mode) 2. Switch to some other window 3. Go back to the fullscreen window There will be a strange title bar at the top of the fullscreen. However, this title bar is actually transparent to any pointer event. I guess it is just something mispainted. This doesn't happen on the current release, but reproducible on aurora and nightly.
Although I cannot reproduce bug 1064787, this patch probably could also fix that bug.

Lets nominate this for aurora and beta uplift once it lands and sticks.
Comment on attachment 8590064 [details] [diff] [review] patch Approval Request Comment [Feature/regressing bug #]: unknown, but seems to be a significant regression since current beta [User impact if declined]: will see unwanted fake title bar on the top, which is hard to remove if the page doesn't change anything on that area [Describe test coverage new/current, TreeHerder]: no test for this particular problem [Risks and why]: doesn't seem to have risk since it just stop system from painting its ui on fullscreen mode [String/UUID change made/needed]: n/a
