Hi,
What happens if the transparent is not set to True? This renders OK for me on
my computer although transparency in general with VTK may not be the best
behaved. It is also possible that your graphics hardware has some issues but I
cannot be sure of that either.
On the UI, try adjusting the degree of opacity and see if that helps at all.
cheers,
Prabhu
