[Paraview] Paraview v5.4.1 using EGL on ppc64le RHEL7.2

[Bruce D'Amora]

using 384.61 driver. Does pvserver use software rendering for surface, 
wireframe, outline, points? Rendering in those modes works, but when I 
switch to volume rendering it crashes. I wonder if I'm just switching to 
H/W rendering when I switch to volume mode and it is crashing.

Hi,

It may be a driver issue. Which NVIDIA driver version are you using? 
According to 
https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/ 
you'll need at lest 355.11.

Cheers,
Andy

I think there is an issue with volume rendering on Paraview v5.4.1 using 
EGL on ppc64le RHEL 7.2 and client-server rendering. Any model that I try 
to volume render results in a segfault.
Always seem to get these errors, but only when I try volume rendering.
