Hmmm...it works for me. That is, I just ran one of my example programs with
various implementations of a coloured surface (multi-cell IDLgrPolygon,
multi-cell IDLgrSurface, single-cell IDLgrPolygon with texture-map image)
and Pickdata seems to report reasonable (x,y,z) data on all of them.

You should expect the same results with the texture-map in place as without.

What specifically is the problem?
