title: Stuttering When Opening New Fragment from Navigation Drawer
body: <p>My app uses a navigation drawer and loads a new fragment into my activity when a row is selected from the drawer. It works ok but there is substantial lag and stuttering on the drawer closing animation. What can I do to eliminate the lag?</p>
