[Inkscape-user] problem (bug?) Wireframe Sphere extension

Hi Friends, I've just been experimenting with the Render > Wireframe Sphere extension, and found some unexpected behavior. Want to make sure if it's a bug or not, before I possibly make an unecessary report. Or maybe there's another place besides LP where it should be reported (assuming it's a bug)? Attached is a PNG export of what I see. These are the settings which produced it, although I tried several other radius values which also produced it. Lat = 8 Long = 16 Tilt = 0 Rot = 0 Rad = 145.0 Window 7, 64-bit, Inkscape 0.91, 32-bit (exe installer) So far, the trigger seems to be the Radius value -- over 100 px gives the unexpected result, and under 100 gives the expected result. I haven't tested with other options. But I could if it would be helpful. Should this be reported? Thank you very much :-) brynn
