Broken Client

As you can see from gyazo link, you can see that my client is completely darkened out. This is the same shade that happens to the background when you choose to accept or decline a game you are about to enter. Me and my friends keep getting this glitch to where if anyone dodges champion select or declines a match, it will make you entire client darkened out and making unable to do press on anything. You can't even exit out unless you us task manager. This glitch Has happened to me multiple times since the new update, Its really irritating and led me to getting another priority queue RIGHT AFTER MY 20 MINUTE ONE FINISHED.
