Black Screen Client

I was in a queue for Blind Mode when I finally got into a game except the Champion Select didn't load. Or if it did it was only for a second; instead, the entire client was black except for the friends/chat/notification bar and the minimize/close. The client returned to normal with a timed ban for refusing to select a champion when I couldn't even see the screen. It all appears normal now (I'm going to restart the client just in case) just thought I should report it in case anyone else had the same issue :/
