Client bug, crashed while in champ select.

Two times it has crashed today. One time, right before the game my league got white, you know crashed. 2nd time, More annoying because i actually lost a promos game because of it, the client glitches, while in champ select the chat goes sideways and everything pretty much disappears until i hover over the stuff. After a player banned a champ really fastly, my whole client crashes and I lose the game because of it. Pls fix client glitch. I think in the last 2 months, ive dodged around 5 games, 5 more than i have ever done, 3 of which were promos games due to these unexpected client glitches. Yes, i have repaired my client a few times. And yes, this is not because my computer is crashing, it's a bug from the client.
