[Paraview] [EXTERNAL] Re: Rendering issue with cross-sections in 3D

[Cory Quammen]

Folks,

The bad news: I can reproduce this in ParaView 5.0.1 on a Mac given
the data files Craig shared.

The good news: I cannot reproduce it in my development version of
ParaView 5.1 RC1. Mind downloading that version of ParaView and giving
it a shot? I would guess there might have been a rendering bug in the
OpenGL2 backend in VTK that has since been fixed.

Thanks,
Cory
