Fred,
What graphics card are you using? And are you saying that more than just the application / applet is flickering? (your desktop is flickering?) On my end, only the applet flickers: the UI and the canvas.
And yes, it certainly does help to know that somebody has seen something similar. Thanks.

Mauricio,
This happens on my antique desktop too. It's so annoying that I
have to exit the browser and restart. Sometimes that clears the
problem, sometimes I reboot. Because the Windows 2000 wallpaper
and desktop seem to be involved, I suppose that it's some
strange system thread priority thing. It's doubly annoying
because it's intermittent, and I don't have a clue about the
conditions that cause it or how to fix it.
Sorry for the lack of help, but sometimes it helps to know that
others are suffering too. :-)

Subject: [JAVA3D] Applet Flickers when Using Java 3D
Hey folks,
I have observed a strange problem using Java 3D on laptops, and
I was wondering if anyone has seen a similar problem.
Our product is a Java applet which uses a Java 3D canvas (a 3D
view) along with some Swing-based user interface components
(e.g. buttons). On laptops using the ATI RAGE MOBILITY graphics
chipset, the canvas and the UI components will flicker
erratically as the canvas is being repainted. Needless to say,
for dynamic operations such as moving the viewpoint (where the
canvas is continuously refreshed), this can be very distracting.
Also, the problem doesn't always happen: sometimes it is there,
sometimes it is not. It has not been observed in native
OpenGL-based applications, or on machines using different
graphics hardware. We are using the OpenGL version of Java 3D
1.2.1 running on Windows 2000, and the latest ATI RAGE MOBILITY
driver (from Dell, the manufacturer of these laptops).
If you have seen this problem or know a way to diagnose it or
work around it, let me know. Thanks!
