When opening an interface (eg crafting menu) while the game is in fullscreen, the mouse is not placed at the center of the screen, but rather in the bottom left quadrant of the screen.

What I expected to happen was...:
Opening an interface and the mouse being in the center of the screen.

What actually happened was...:
The mouse was in the bottom left quadrant of the screen

Steps to Reproduce:
1. Open any game in minecraft and put the game in fullscreen (either through menu option or F11)
2. Open an interface, such as inventory, but don't move the mouse
3. Notice mouse is not centered.
