A JFrame created with opacity set to false do not show up on a Windows XP system with Intel 82865G graphics card. I can see the frame icon on the task bar but nothing is shown on screen - I've a button on the transparent window, but thats not shown.

I'm running the below program:

import javax.swing.*;
import java.awt.*;
import com.sun.awt.AWTUtilities;

public class Test {
    public static void main(String[] args) {
        JFrame f = new JFrame();
        f.setSize(200, 200);
        f.setLayout(new FlowLayout());
        f.setUndecorated(true);
        f.add(new JButton("Click Me"));
        AWTUtilities.setWindowOpaque(f, false);
        f.setVisible(true);
    }
}
