Hi Ian,

This sounds like a heavyweight/lightweight issue. Sun has a good
overview of the issue at:
http://java.sun.com/products/jfc/tsc/articles/mixing/
However, it was my impression that DisplayImplJ2D is not a
heavyweight component (the heaviness is a Java3D issue, so
DisplayImplJ3Ds are heavy, but VisADCanvasJ2D extends JPanel,
and should thus be lightweight).

I don't think you are the first person to mention this problem.
However, I've never seen it happen myself. You could always try
calling validate() and/or repaint() on your GUI manually, to see
if that does the trick.

I'm not positive what's going on here either. Are you calling
setAutoAspect before doing pack() on the window? The auto-aspect
logic only kicks in when setBounds is called on the display's
GUI component. It may also be that VisAD is re-rendering the
data in a separate thread, and thus you're seeing the old
projection for a moment before it completes the new projection
based on the adjusted aspect ratio.

Again, this sounds like the heavyweight/lightweight issue,
but that's just a guess.
