[Paraview] volume rendering with Catalyst ...

[Andy Bauer]

Hi,

Are you generating the Catalyst script with PV built with the OpenGL2
backend and then linking with a version of Catalyst built with the OpenGL1
backend? I'd guess that this is the problem.

To isolate the issue further, you can do a Python trace in the GUI to see
if you get the same issue when you run pvpython with that script.

Best,
Andy
