Entire screen flickers with 1.2

Name: el35337 Date: 04/08/98


I've reproduced this on two different NT machines,
both of which have an "s3 compatible display".

When I run the program below, any time I move the
Frame of the running application, my entire screen
flickers wildly.

If I decrease the refresh rate on my monitor, the
problem is not as bad, but then the screen as a
whole doesn't look as sharp.

This problem does not reproduce under the JDK 1.1.

Here's the test case:

import java.awt.Frame;
import java.awt.Image;
import java.awt.Graphics;

public class Test extends Frame
{
private Image m_img = null;

public Test()
{
}

public void paint( Graphics g )
{
if ( m_img == null )
m_img = createImage(100, 100);
g.drawImage(m_img, 40, 40, this);
}

static public void main( String args[] )
{
Test t = new Test();
t.setBounds(100, 100, 200, 200);
t.show();
}
}
