Dropouts? Is it a bug?

Hello every one,

I render a number of polygons that make up rooms, kind of indoor scene. I notice weird droopouts where two polygons share the same edge. Each polygon is rendered as a separate triangular strip.

Is it a bug in my GeForce 2 MX 400 card? or is it a driver bug? I’ve the latest drivers installed.


I gues I figured out the answer. If an edge is shared between two polygons whose vertex order is the same (both CW/CCW), then the edge is visited differently for each polygon.
This results in slightly different set of pixels describing the same edge.
