runtTimePostProcessing issues with interpolated
As @Prashant noted during testing, the unlikely (undesirable) combination
- a sampled cutting plane with interpolate = true
- rendering in parallel
The result looks like rubbish. If we switch to VTK rendering in serial - works fine, so the problem is not in the sampler.
Normally we would use 'interpolate = false' when sampling, but use 'smooth = true' for viz to get pretty pictures.
Needs more investigation
