        softButton1.setBackground(Color.GREEN);

        this.setBackground( new Color(0, 0, 0, 255) );
        
        add(softButton1);
        add(softButton2);
        
        this.setVisible(true);
        
            
        softButton1.setAlpha(.05f);  // on press flicking 
        softButton2.setAlpha(.05f);  // on press flicking 
 
              
    }

1) The JWindow() or Window() is having a attachment with webCam (progressive scan)

2) When Swing button JButton() is used it start flicking and does not work, but Awt Button() works, in that case only is the issue to put image

3) Transparent can be done with JPanel() but not Panel()

Mixing Awt and Swing solves it, but would be nice to do it in Swing only. Already you can see its not working. Where 20 frames per second crash the JButton visibility and creates flicking problem

Hope its very clear? Please let me know if you can find solution.
