Thanks Kelvin,
Yes the problem seems to occur only with JDK 1.4.0. It seems though that one "paint()" event comes through, since the canvas is fully painted when I click on the title of the frame. The gray area comes when I move the mouse to the canvas.
The -Dsun.java2d.noddraw=true didn't fix this problem.
I also got a bit similar behaviour with the FourByFour demo. When I launch it from JBuilder, the canvases are grey as shown in the attachment. I have to put another window on top of it and bring it to top again to see it, but then I see it all. When I bring it to top I think I see a glimpse of such a gray area, but it disappears.

Hi,
Seem to me the swing fail to deliver "paint()" event to the
heavyweight Canvas3D. Mixing heavy and light weight component
in Java is known to be problematic.
Try to use the switch
java -Dsun.java2d.noddraw=true yourApps
(which is required to use JDK1.4 fullscreen API with
DirectX version of Java3D)
The following bug may be related.
4665482 - Missing first paint() event under JDK1.4 windows version
You can also try to isolate the problem by using JDK1.3.1.
Thanks.
