Black screen in champs select

I don't know if it's really a bug but i just got a black screen in champs select i couldn't pick a champs and got removed from the ''queue'' and got a 5 mins penality for it so yeah and btw you guys should add a report a bug in the client cuz it's kind of a pain to have to open internet go to the websites clic on the boards section go to report a bug create a discusion then start writing so maybe just a little add on for poor sloth like me ;)
