Screen Lock

After I updated the client I went into a ranked game. Once in the game I realized my screen was locked with a red border around it. No matter what mode I was in, it would not unlock screen. I usually play in borderless mode but tryed windows and fullscreen, none of which worked. I went into a custom game afterwards and the game was just fine. Don't know if this is a bug or no but wanted to report it in case other players are experiencing the same thing.
