Steps to reproduce:

Just a part of the video get in fullscreen, the other part of the screen are still black. Also the timeline and youtube control stops in the middle. (it's hard to explain, just look at the attached screenshot)

Expected Results:
The Video should be show in the hole screen.

Additional Information:
If you get in fullscreen via the html5 control, it works.

The <video> element has width and height specified in CSS in absolute pixel coordinates. Changing the pixel size in CSS makes the video size correctly.
