The android project window spends a lot of time being updated/refreshed during a gradle synch.  This became a noticeable issue with this last update of android studio.  As the gradle synch is being performed that window is constantly be updated.  I see closed folders open up and close and it just goes crazy.  In the previous version, I never noticed that happening or it wasn't particularly noticeable.  It may be that its caused by the various folders being automatically opened during the synch process.  (Note:  if you're trying to replicate this behavior, make sure to test it with a project containing multiple modules in it)

Even when the gradle synch finishes the Android project window can still keep on being updated or refreshed.  When that happens,  if I switch to the Project view window an then go back to the Android view window, that crazy updating stops.
This seems to only be a problem performing a gradle synch with the Android view window opened,  If you have the Project view window open instead when you do the gradle synch it's well behaved.
