The bad news: I can reproduce this in ParaView 5.0.1 on a Mac given<br>
the data files Craig shared.<br>
<br>
The good news: I cannot reproduce it in my development version of<br>
ParaView 5.1 RC1. Mind downloading that version of ParaView and giving<br>
it a shot? I would guess there might have been a rendering bug in the<br>
OpenGL2 backend in VTK that has since been fixed.<br>
