java3d in Ubuntu 9.10 can't update screen promptly...

Hi, all:

Urgently need your help.

I met this problem long time ago and till now, I couldn’t have managed to solve it. Unlike in Ubuntu 8.10, Java3D seems to be incompatible with my current Video driver in Ubuntu 9.10.

I uploaded a video at
http://www.visionopen.com/java3d_ubuntu910.ogv

As shown, Java3D is not able to erase the old leftovers whenever I move the canvas to a different place.

Did anybody meet the same problem and is there a way out to eliminate this terrible problem of display?

Looking forward to your kind and prompt help.

Best best Regards
JIA Pei
