Now that is just plain weird! :)

Ok. I can get rid of the lines, but here is how I had to do it. I took Alekssander's idea of messing with 3d view quality.

I HAD to have to the max and the background draw HAD to be no higher than that. Strange but that was the ONLY way I could get rid of those lines. Any less instant draw and the lines are back. Won't it slow things down having it that high?
