Hrms, I've removed the code already for zbuffer value checks, it was  
just too unreliable with edges or slightly non-planar quads. I also  
wanted to have proper edge selection for subsurf-optimal draw, not  
possible with previous method. Plus the zbuf method didnt even work on  
linux with newer ATIs.

I rather check on what exactly is wrong with your gfx setup. Whats your  
card? OS? I can give some hints for (or a patch) with prints in the
