Since I have start using JDK 1.2 RC-1, I am getting
problems with repaint on all swing widgets. This problem
does not exists under JDK 1.2 Beta4 or JDK 1.1.6.
I am developing under Wni95 v950B and
WinNT v4.0.0.1381.

Win95 hardware setup:
IBM 300PL with Matrox Mystique
Accelerator 1164SG RAMDAC 220Mhz
Memory 8Mb Memory type SGRAM LVTTL 8 MBits
VGA BIOS: 1.5
Display driver 4.10.01.4120 DirectX 6.0

WinNT hardware Setup:
Dell OptiPlex GX1 with ATI 3D Rage Pro
Chip Type ATI 3D Rage Pro AGP 2X (GT-C202)
Driver Version 5.0.112, 4.0.0

I just want to say that JDK 1.2 RC-1 works fine with my other Video Card
(nVida Riva AGP 4Mb AMD K6-2 128Mb RAM PC100)

A simple menu bar with menu items doesn't display properly on my Windows 98 machine.

When I bring up a simple Java Swing menubar, and move around in it, I see a lot of artifacts created. For example: only parts of the menu items are highlighted, and purple trails are left behind.

This seems to be a known problem, as I found it mentioned in one of the Java newsgroups. (comp.lang.java.gui).

If I disable Direct Draw, by renaming c:\windows\system\ddraw.dll, the problem goes away.

I have an ATI Rage Pro card (ATI Rage Pro Turbo AGP 2x w/ 8M RAM). I upgraded to the latest driver from ATI's site recently. The driver upgrade had no effect on the problem.

Direct X 6.1 is installed on my system.
Also DDRAW.DLL is version 4.06.02.0436 (1-8-99).

I have a BMP file illustrating the problem, though I see no way to attach it here.

The code for one such menu (all have the same problem) is:

/*
A basic implementation of the JFrame class.
*/

import java.awt.*;
import javax.swing.*;
import java.io.*;

I encountered this problem when I created a JFrame and added a JDesktopPane to it. I then added a JInternalFrame to that, and a few JMenuBars to the original JFrame. Whenever the mouse is moved, a blank spot on the screen is left where ever the mouse was. When I move the JInternalFrame, the title bar gets messed up and when I select a menu, JMenuItems get scrambled when I move the mouse from one to the next. I am using 1152x864 16 bit resolution with a Mag Innovision model 720 V2 monitor. My video card is a Diamond Stealth II S220.

I am developing an application that will eventually run on a client's laptop. In
test versions of the app. on his laptop, we've noticed some strange "ghosting"
effect with pull-down menus.

this definitely has something to do with his video card because, when he turned
off "hardware acceleration", the problem disappeared. here is a profile of his machine:

- Dell Pentium II 300 mHz
- OS: Windows 98 4.10.1998 (Build 1998)
- Video Card/Driver: ATI Rage LT PRo AGP 2X (12/11/1998)
- Video Memory: 8 meg
- output of "java -version":

java version "1.2.1"
Classic VM (build JDK-1.2.1-A, native threads)

here is the example program that i used to reproduce the problem:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class menutest extends JFrame
{

  menutest()
  {
    super("Menu Test");
    setSize(300, 100);
    addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e)
{
System.exit(0);
}
    });
    JMenuBar mbar = new JMenuBar();
    JMenu m = new JMenu("File");
    m.add(new JMenuItem("Test1"));
    m.add(new JMenuItem("Test2"));
    m.add(new JMenuItem("Test3"));
    mbar.add(m);
    m = new JMenu("Edit");
    m.add(new JMenuItem("Test1"));
    m.add(new JMenuItem("Test2"));
    mbar.add(m);
    setJMenuBar(mbar);
    setVisible(true);
  }
  
  public static void main(String[] args)
  {
    new menutest();
  }
}
