This is a very minor bug but in any loading screen if you click the middle of the bottom part of the screen(see screenshot below), it will make a clicking sound like if you click the cancel button when locating a server(see screenshot below) but it will not do anything. It is most obvious on a offline server. when you click on the server a locating server screen without a loading symbol or cancel button(see screenshot below) will appear and is a good way to test it.
