If you quit the game in full screen mode, it will chop off the bottom inch or so of the picture when you restart the game.
The expected result is that it display the screen properly without cropping off the bottom of the picture.
The actual result is that the picture is cropped and you can't see the Minecraft version in the main screen or the hot bar in game.
