New League Client going completely black.

I haven't had any troubles with the new league client in the past while it was in beta. But just recently it's began doing something weird where occasionally when my que pops and I get into champ select the whole client goes completely black and I can't see anything. I can still hear the banning in the background and people selecting their champions, but I just can't see anything. This is very frustrating because when this happens after I que up in ranked, I lose lp for not being able to lock in my champion plus I get put on long dodge timers. Please fix riot ):

Sincerely,

A hard stuck Silver 1 player.
