Instead of processing.opengl.* this example uses javax.media.opengl.* and com.sun.opengl.util.FPSAnimator. You may avoid some strange sideeffects Processing gives you by adapting other Java JOGL stuff…

If the source of your hack is not overly long, it'd make sense to paste it in here. In anyway you should also offer a zipped up sketchfolder of your hack as download in the section below

  FPSAnimator animator = new FPSAnimator(canvas, 60); 
  animator.start();
