Do you have a dataset to reproduce this issue? There were changes in<br>
the reader in this past release, so it's conceivable that it<br>
introduced a bug.<br>

Presumably the cell ordering will be preserved in both cases, but still not 100% trivial. Either way, we need to figure out which cell types are causing the issue, or an off-by-one of whatever.<br>

> I have no polyhedral cells (hybrid tetrahedron/prism mesh), so I guess changing "decompose polyhedral on/off" does not make sense. In fact the smaller mesh that I tested with before did show the correct visualization and that mesh had polyhedral/hexagonal cells. It did not matter whether I used decompose polyhedral on/off. I also have experienced the slicing issues from time to time with various paraview versions with polyhedral meshes, but the effect was typically much less severe than in the current situation.<br>
