Tolerance related rendering issue
Good afternoon ParaView team, this is the first time I've ever submitted a bug/issue report here so forgive me if I leave out anything obvious.
I have a CGNS grid file wherein the smallest elements are very small compared to the largest as well as the overall size of the mesh. The smallest elements (which are on a boundary) appear improperly rendered; they seem jagged and perhaps crossed. This happens in release versions 5.6.2 and 5.8.1 on Linux at least; I have not tested any other versions/OSes. I have a colleague who has verified that this mesh renders as expected in both VisIt and TecPlot.
If the extents of the mesh are clipped sufficiently, the poorly rendered elements are properly rendered. The steps to reproduce this clipping are as follows:
- Clip Type: Sphere
- Center: approximate center of interior circle
- Radius: 1
- Crinkle Clip: checked
See screenshots below:

Lastly perhaps one more thing that is relevant is that the mesh points seem to be rendered properly, just not mesh edges/elements; see screenshot below
I have attached the CGNS file here in this issue that I use to reproduce this issue. Please feel free to follow up with any questions or for any details I may have left out. Thanks for you help!
