I see, these are 3D lines. I will look at it, hopefully during the next
week.

I wonder if this happens only when the line is draped over a surface, then
it's drawn as many lines. I don't think there is a simple way to set line
caps in openGL, so I doubt I could fix it.

does this happens with recent grass? I thought I fixed something similar
to what you describe sometime in summer, but it might be a different
problem. If it happens with recent GRASS, could you send me the data (or
show the problem on nc_spm)?
