Utkarsh, Forgive me, I should have specified how I was running the server. Here is the command I used that resulted in the strange behavior:
mpirun -np 4 pvserver -display :0 --server-port=11111 --use-offscreen-rendering It seems to work fine for all rendering aside from volume rendering of unstructured grids.
