If you are in a window and switch to fullscreen in Ubuntu 14.04 LTS, you can only move your mouse approximately 180 degrees unless the game paused and unpaused.

What I expected to happen was...:
Enter fullscreen mode and be able to completely move my mouse

What actually happened was...:
I can only move my mouse approximately 180 degrees

Steps to Reproduce:
1. Have a Minecraft world open, single player or a server as long as it is in windowed mode
2. Enter fullscreen by pressing F11

It isn't that big of a deal, cause you can fix it by pausing and unpausing, but so much of a nuisance that I came on here. See the video for details
