[Paraview] Paraview and tiled display

[Greg Abram]

Can't believe I never tried this before - I'm trying to use PV to render to a tiled display with 2 nodes driving 2 screens each in TwinView mode, and oriented one above the other.  Initially, all is well - the target screens show the grey background with the axes centered and the screens are filled.  Just what you'd expect.  Then, as soon as I put some geometry into the display (such as the Sphere source) smaller windows appear on the tile displays, one showing the top half of the correct image and the other the bottom, but clipped to the bounding box of the data.  Like the results of the first pass of a binary swap compositing -  data from both processes shows up in each.   When these windows appear, the rest of the tile displays revert to the original desktop background.  If I add --use-offscreen-rendering to the pvservers the two smaller windows still appear, but are black.  

So - how do I get rid of those windows?   And is there a way to suppress rendering to the PV client?

Thanks,
Greg
