I've uploaded a video of this problem here: https://www.youtube.com/watch?v=AtNLZDXvsn8

This happens when exiting from spectating a game, when leaving a custom game, and from how it functions it may occur when disconnecting from normal games. It does occur consistently if you do not move your move - as was done in the video - but it does happen at other instances. The exit game button functions as a reconnect button.
