Mac Mavericks Bug. Anyone Else Having These Problems?

Ever since I upgraded to the latest Mac client Mavericks I can not play a match without switching screen size, only being able to ping danger, and not being able to click to the lower left of my screen among other things. I can temporarily fix the problems, but it only last for the match and takes about 2 minutes and have to do it every match. It's really annoying and can't seem to find a solution. Anyone else having these issues?
