When you were using listS as the vertex container, you were creating a 
vertex_index property but not initializing.  Thus, the vertex_index values 
were most likely all zero, and so all vertices were mapped to the same 
location in the displacement map.  Switching to vecS made the vertex_index 
property auto-generated with correct values, fixing the bug.
