This 'jerky' behavior is well known, see bug

Today or tomorrow I may finish my 1st draft of the FBO offscreen
drawable, allowing resize w/o recreation of drawable/context.

On OpenJDK 1.7 the AWT related GLDrawable is always offscreen
as with Applets on OSX >= 10.5.8 and Java6 - since it's the only
JAWT hook they provide (CALayer).
