After a game or so of League of Legends or Counter-Stike: Global Offensive, my rMBP's animations just ... "stop" with the track pad. Basically, the dock's hover animations don't work, the shadow/hover animation of tabs on Safari or anything to the matter stops working. The trackpad itself works outside of game applications, but suffers the animation problem and sometimes UI lag (3 finger move window doesn't work/works but is VERY delayed - by 5-10 seconds). In-game, the trackpad doesn't work after the issue begins. I am using the 2012 rMBP, a Razer Deathadder, and the only extension I think may cause a problem is "SmoothMouse."
