What's Wrong?

after running cc for about 2 hours, everything slows down significantly. not just within cc (i use it within cursor) but generally on my system. the mouse starts to lag, scrolling lags, and everything generally becomes slower. i dont hear the fans going off, i think its memory leaks and heap related. might be the git cache. didnt have these issues before the 2.0 upgrade.

What Should Happen?

no lag
