One issue that plagues me is that full-screen apps sometimes don't take up the entire screen. They're still allocating space for the menu bar. Lo and behold, there is an invisible menu bar there. Sometimes the apps still draw a (totally nonfunctional) window title bar. This only ever happens with Sublime Text, iTerm, and Chrome Dev Tools. Id est the three apps that I spend 99% of my time in. Quick Look also has severe performance regressions. It takes ~20 seconds to open the first time. Not so quick, eh. I suspect App Nap is at fault here.
