My game keep crashing when I try to press Windows button (when the game is fullscreen) trying to go desktop.

The game also lag a lot but I made another report, I said it because I thought it can be a related issue.

EDIT: This does not happen is main menù, only in my new world (created in 15w45a but I have not tryed with each others)
