I have a frame , which contains a desktopPane. I can see the Incorrect painting at the right top corner of the frame. This is not seen on other LookAndFeel. I have attached the screen shot of the same. I tried even resizing the frame & it disappears only when the size of the frame is very small.

Step to reproduce :-
-----------------------
1) Run the below testcase.
2) Observe that top right corner of the frame. you will a while patch . If you see the same then the bug is reproduced.

I tested this on jdk1.6.0_10 b09.

---------- TestCase -----------
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JDesktopPane;

public class NimbusFrameBug {
JFrame frame = null;
public static void main(String arga[]) {
javax.swing.SwingUtilities.invokeLater(new Runnable(){
public void run(){
new NimbusFrameBug();
}
});
}

NimbusFrameBug(){

frame = new JFrame("NimbusFrameBug");
int inset = 50;
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
frame.setBounds(inset, inset,
screenSize.width - inset*2,
screenSize.height - inset*2);
JDesktopPane desktop = new JDesktopPane();
frame.setContentPane(desktop);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);

}
}
