Aubrey,
>From the screen snapshot you sent, I have the impression you are exceeding the
resolution of your Z buffer. Try reducing the ratio of far/near clipping
planes. Reduce far or increase near distances. Also, if possible the white line
can be drawn in post-draw callback with zbuffer off. Or maybe you can raise the
line a little bit more above the ground.
Good luck.
