Hi Yuri,
Cool effect ! This happen under opengl version
when hardware antialising is not support. In this
case accumulation buffer is used for multipass
blending. Obviously fieldOfView is not taken
into account when computation the jitter offset.
Bug 4634877 -
Antialiasing using accumulation buffer did not take into
account FieldOfView
is submitted for investigation.
If you graphics card driver support antialiasing
under DirectX, try DX version of Java3D to
workaround it.
Thanks for your bug report.

Hi Kelvin,
Thanks for your response.
Your test program does not present the problem indeed. However, this is only
so since the scale of your geometry is in the order of 1. I modified the
code so that the color cube is 100 times smaller, slightly changed the
viewing platform settings to see the cube the same way as before, and look
what that does to the cube! Work of art.
Please find the modified test program in the attachment. You can change
mScale parameter to magnify the effect: smaller the scale - worse the
jittering.
Yuri.
