I’m not an expert, but for some reason it seems to me that this is a display resolution issue. My case, for example: I have a tile texture for my floor, and everything normally looks fine, but when you look at it from a very low angle, all those lines representing spaces between the tiles get too close to each other and start flickering since the display resolution is just incapable to show them properly. Your geometry is really tiny, and you’re trying to fit about 30-40 lines in 20 or so pixels.
Will a user be able to get really close to see all that geometry? Maybe it would be better to a material with a normal map, where you can change anything depending on the distance to camera?
Again, I’m not an expert in rendering issues, so you can ignore all the above =)
