OK,
so you've given us a SSCCE in the form of the Pyramid example, and you've tried the code I suggested (Java3DSimpleTest).

I presume, given that you mentioned the sync work around that's on the net, you also tried
 Canvas3D canvas3D = new Canvas3D(SimpleUniverse.getPreferredConfiguration()){
            public void paint(Graphics g) {
                try {
                    Thread.sleep(100);
                } catch (Exception e){}
                super.paint(g);
//                Toolkit.getDefaultToolkit().sync();
        };  

?? If not please do :) .

Can you confirm that the grey is coming from the Canvas3D component parent by putting canvas3D.setBackground(new Color(1,0,1)); in and see the grey become a pink. If it doesn't then the problem is probably not with Canvas3D redrawing and we can attack other avenues of investigation.

Thanks,
Phil.
