I have Ubuntu 12.04 64bit installed/full updated and have noticed that I can only play 1080p youtube videos properly on full screen. All other resolutions, 480, 720, 1440 etc do not go into full screen properly. Please have a look at the attached images. You will notice that only the 1080p video has the video control bar right at the bottom with a respectable text size. All other videos don't have the video control bar right at the bottom on the screen, and the control bar text is too small.

I've had this problem for ages, but finally decided to ask about it.

480p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides:

720p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides and the text is tiny:

1080p: This is the only one that works as expected, i.e. controls right at the bottom, and good font size and no borders on the sides:

1440p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides:

How do I correct this problem so I can play all different video resolutions at full screen.

The flash version I have installed in Chromium is Adobe Flash Player - Version: 11.2 r202 - Shockwave Flash 11.2 r202
