Odd. I wonder if it's driver related. Did you build ParaView with VTK_RENDERING_BACKEND set to OpenGL2? Also, "-tdx"/"-tdy" could indeed slow things down as it's now rendering for a tiledisplay rather than for a client. The rendering works in that case, since the client is rendering on it's own. Also what is the datatype you're rendering? I'd suspect it's an unstructured grid or a multiblock of unstructured grid.
