That might be the main cause of this effect.
Yes, indeed. It is (or ought to be) possible to adjust the Z-buffer value for fragments to reflect their new "position" as determined by the relief computation. This would solve depth problems between the ground triangles and objects on them but will not help for the problems along the edges of the urban area since the urban shader is not run for the fragments of the adjacent ground triangles and consequently a relief "building" cannot occlude those fragments. There might be other tricks to make the transition to other ground types more pleasing, though.
