[Paraview] Errors with GPU-based volume rendering

[David E DeMarle]

Sounds like a bug then if 3.8 works and >3.8 doesn't on the same
setup. It suspect it is in the new rendering architecture that was
introduced with 3.10.

Please file a bug report with enough information to reproduce the
problem so that we can keep an eye on it.
