Java Applets do not Refresh Screen Using Matrox Video Card

When you run a Java applet on a multiprocessor computer using a Matrox MGA Mellenium video card, the applet window is erased when moving the window around the screen. The applet window goes white and does not refresh after being moved. The Java applet window may also leave blotches of the white screen behind after being moved.

The symptom is more apparent in true color.

This problem does not happen on the same system running one CPU.


Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
