[Client] Goes into windowed mode when entering game

I have no idea what is causing this but spontaneously the client went into a windowed state with the window being too large for my screen and showing part of the top border. As such I couldn't scroll the screen downwards or see the bottom of the client on my screen. Interrupts gameplay! Tried restarting the client and now when ever I enter a game it will go into a windowed mode. Attempting to repair client now... Will report back if anything changes
