You can also use the Z key, it works the same as middle click!
That's a thing browsers do if you click somewhere outside of the game's display area. Do a mouse click on the game's window to fix that
This happens because the fullscreen button isn't a part of the game, so clicking it to enter fullscreen unfocuses the game. Just click your mouse after going into fullscreen to fix that!
