Yes, the depth buffer for the context seems to be missing.  The person who
submitted the QGLWidget patch had exactly the same issue:
https://gitlab.kitware.com/vtk/vtk/merge_requests/1097

That was for linux on a virtual machine, so I thought it was the fault of
the virtual machine.  But maybe it wasn't after all!

I use linux as well, with NVidia graphics, for me it works without
QGLWidget.
