I hadn't followed this conversation because I saw it mentioned it was
a Linux graphics issue, and then you mentioned it was a driver issue.
Out of curiosity I ran the conical_cut script on my Windows 10 machine
with Octave 5.1.0 and switched graphics_toolkits. With qt and fltk I
get the half circle, with gnuplot I get the full circle. I don't have
access to enable/disable hardware acceleration to see if it's an
issue. So if it's an OpenGL driver issue it's cross-platform.
