Point appereance as square or sphere depending on GPU driver settings

[freecad-heini-1]

Hi,
it's interesting to me, that a Freecad point can have different appereance depending on the GPU driver settings.
It concerns a Nvidia Quadro P200, running on Xubuntu 16.04. If I change the settings from quality to performance, the look is different. Please have a look at the following pictures:

With quality settings the point look like a sphere. Very nice.

Best regards
Wilfried
