Clipping a VTX file randomly deletes cells -- but crinkling brings them back!
I'm fairly sure this is a regression. See the attached video for a visual description. vokoscreenNG-2023-02-09_15-21-17.mkv
Interestingly, if I open just the mesh file in xdmf format, clipping works fine, so it seems to be related to VTX somehow.
For completeness, info on the VTX file:
