title: Java Swing rendering bug on Windows 7 look-and-feel?
body: <p>The knob on vertical JSlider's on my Windows 7 machine (with native look-and-feel) is really, really tiny in both directions. Not just skinny but short as well. <a href="https://i.stack.imgur.com/PmmPR.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PmmPR.jpg" alt="alt text"></a>
  </p>
  
  <p>Can anyone confirm this? Should I report it? If so, where? Thanks!</p>
  
  <p>Here is the code for the sample program (in the screen shot):</p>
  
  <pre><code>import javax.swing.JFrame;
  import javax.swing.JPanel;
  import javax.swing.JSlider;
  import javax.swing.SwingConstants;
  import javax.swing.UIManager;
  
  
  public class SliderTest
  {
      public static void main( String[] args )
      {
          // Set the look and feel to that of the system
          try
          { UIManager.setLookAndFeel( UIManager.getSystemLookAndFeelClassName() ); }
          catch ( Exception e )
          { System.err.println( e ); }
  
  
          // Launch the GUI from the event dispatch thread
          javax.swing.SwingUtilities.invokeLater( new Runnable()
          {
              public void run ()
              {
                  JFrame window = new JFrame();
                  window.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
  
                  JPanel contentPane = new JPanel();
                  contentPane.add( new JSlider(SwingConstants.HORIZONTAL) );
                  contentPane.add( new JSlider(SwingConstants.VERTICAL) );
  
                  window.setContentPane( contentPane );
                  window.pack();
                  window.setLocationRelativeTo( null ); // Center window
                  window.setVisible( true );
              }
          });
      }
  }
