J3D and Fullscreen

Question

I'm working on a simple engine for 3d online games (a demo can be found at http://www.elet.polimi.it/upload/arrigoni/j3drpg.html).
I see that with many but not all the video cards Canvas3D simply does not update, but input and behaviors work propertly.
I distilled this simple example:
import javax.swing.*;
import javax.media.j3d.*;
import com.sun.j3d.utils.universe.SimpleUniverse;
import com.sun.j3d.utils.geometry.ColorCube;
import java.awt.*;
public class Test
extends JFrame
public Test()
setSize(800, 600);
Canvas3D canvas3D = new Canvas3D(SimpleUniverse.getPreferredConfiguration());
getContentPane().add("Center", canvas3D);
BranchGroup objRoot = new BranchGroup();
objRoot.addChild(new ColorCube(0.5));
SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
simpleU.getViewingPlatform().setNominalViewingTransform();
simpleU.addBranchGraph(objRoot);
public static void main(String[] args)
Test test = new Test();
test.setUndecorated(true);
// test.setVisible(true);
GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice device = env.getDefaultScreenDevice();
device.setFullScreenWindow(test);
If I use "test.setVisible(true)" it works fine but if I try to display it in fullscreen Canvas3D is WHITE... (but other components can be correctly displayed)
can anyone help me?
thx

What OS are you on? I know that thefolk who are working on the Jight Weight Java Game Library which is an OpenGL library (Did you download the OpenGL or DirectX version of the Java3D API?) are having troubles with getting a white screen on OSX machines. They seem to think it's connected with high screen resolutions, so if this sounds like your setup, you may look into it. Or if you have your screen set to an extremely high resolution anyway, it couldn't hurt to look at it!
