Ranked Champ Select Black Screens and Random Freezing

I have been getting tons of black screens in all my champ selects recently.

In a ranked champ selection my entire client froze and the game started. Once I reconeccted after 5 minutes it was a remake, and I lost 20 LP, which is disgusting being that it was not my fault the client bugs out wierdly and whenever I try to change a summoner the entire thing freezes.

-- If it happens again I will attempt to screenshot it...
