Noticeable Lag in client/ champion select

My Personal Experience when getting into a game is that there are moments where the client chokes and stops causing me to be unable to do anything in the client. When I was in champ select for my first game after the patch and noticing that when im trying to select masteries that it was lagging to the point where I was unable to click on anything causing me to end up with almost no masteries that game. If there is a fix to this I would love to know but currently the client update is a thumbs down for me.
