@PetrKryslUCSD – I mentioned this a couple years back:

Whenever a non-zero Nonlinear Subdivision Level is used, to show the curved elements, “speckles” appear on the surfaces and the surface edges become “dashed”. The default setting for NSL is 1, so by default these meshes look… unprofessional (i.e. not suitable for publication). Is there a setting that I need to activate in order to properly visualize higher-order meshes in ParaView? [This isn’t the first issue I’ve se…](https://discourse.paraview.org/t/raytracing-nonlinear-subdivision-level-surface-with-edges-draws-too-many-edges/5648)

The workaround, provided by @utkarsh.ayachit, is to

> …add a pass through filter like Calculator or AddFieldArrays and then render that as wireframe while rendering the original dataset as surface.
