When entering in full screen by both way (F11 or in the option), the screen get puzzled like we are seeing à bit of the screen and everything is leaning. No hotbar, nothing.

The only place where the bug don't seems to appear is the main menu, but if you enter in the multiplayer menu or somewhere else, it appear again.

The bug is showing on all snapshots since 14w28b

On the screen you can see the 2 views.
