[Client] Going Black In Champion Select Screen

When entering champion select, on some random occasions the entire client goes black. Nothing is clickable other than the group chats and the minimize/close button. However, it still acts as if you're in said champion select when you try to close out of it, and it results in forcing you to close your game and take the 5 minute wait time penalty for queue dodging. Again this seems to be completely random, and its only happened to me 3 times so far (ive had this for a month and a half) and its a bit of an inconvenience and annoyance.
