This only happens in a Mac but needs to be resolved.

when you split-screen and set the Minecraft to fullscreen. It took me a while to sort it 

out, In the end i did it. this might confuse new players and annoy them. here is a picture of what happens:

If you try to exit full screen screen it crashes the game.

Please solve this.
