Trying with Windows 10 as well as Ubuntu 20.04, I can only reproduce the option "Vertex" making problems. Everything else seems to work, but this option is not shown in any of the 2D views, only in the 3D view. I used openMeAlone.mps and PointSetForPic3D.mps.

Correction to my previous comment: all options are rendered. The only thing is, that the "Vertex" option is hardly visible because it is so small in the 2D views. Since the vertex does not change size with the scale property, I would assume this is by design.

I expect a circle in the cross-hairs, akin to Shape: cross or vertex. But there is None. Is this expected behaviour?
@s434n is right. Vertex is almost invisible although exists.

I think this is due to some weirdness in the data. testPointSet does not seem to have any dimensionality, so my guess is this messes with the 2D rendering. It looks the same for me, but works fine with other test pointsets (e.g. openMeAlone.mps and PointSetForPic3D.mps from the TestData folder).

Ok, I got it working as well. Thanks!
We can mark it resolved.
