title: Android Studio becoming unresponsive
body: <p>Just moved from Eclipse to Android Studio a few days ago and everything seemed fine. Now after using it for a while I've noticed that it sometimes, seemingly at random, becomes completely unusable. The UI seems to hang for five or so seconds, then everything is alright for a couple of seconds, then hangs again. The "wheel" animation at the top right of the package explorer is spinning constantly too, but again this happens even when I've just left it for a while (No coding, no running projects etc...)</p>
  
  <p>Update: Seems to start the wheel animation when I use the Full Screen mode and slowly gets more sluggish. Switching back to windowed mode after does not solve the problem.</p>
