I don't say there is a problem with this in Irrlicht, but sometimes i get different

How does Irrlicht handle this?

PolygonOffset has been implemented. It appears to be a material parameter: PolygonOffsetDirection, PolygonOffsetFactor.

just do it in the shader.... save yourself the incompatibilty issues
