If you have a message at the "player count" in the multiplayer menu it can be displayed even if it is under the buttons. To make this bug happen, you can add servers and then put the mouse on the buttons, and if you are lucky you can find it where it says like "50ms".
Environment
Windows 8, 64-bit Java update 45, Connected to the internet without any other programs running.
