Grid rendering incorrectly in glviewer

I have tried grid on two computers
- laptop, Ubuntu 14.04, qt4 build, with the same problem you showed on
the picture.
- desktop, Ubuntu 15.10, qt5 build, and it looked smooth as I would expect.
So qt4 vs qt5 could be one reason. However, some other software or hardware
differences may be the source problem as well, I am not really familiar
with this issue, so probably somebody else (Anton?) could help more..

renderer = yade.qt.View()
renderer.grid = (True,True,True) # or some other combination of True/False
for x,y,z

Difficult to say, it can be a graphic driver problem.
Anyway for a real post-processing I would recommend
to use VTK export.

Thanks Jan Stránský, that solved my question.

One more thing, is it possible to have the minor gridlines appear from the start in the python code as well? I.e. what happens when you press period in the viewscreen.

Thanks Jan Stránský, that solved my question.
