Summary0003936: Off by one pixel multiview windows
DescriptionWhen you are in client server mode and are doing image compositing, there is sometimes an off-by-one error that occurs when reading back images when you have multiple windows. Sometimes on the left and/or bottom there is a pixel-width worth of image read back that is garbage.

The arithmetic in vtkPVDesktopDeliveryServer is probably wrong. My guess is that it is computing the offset of the viewports to be a little too far to the upper left.

Ken, can you verify if this is still the case?

Sometimes if I crank up the subsample rate and/or resize the window a lot, I can see some errors around the view edges during interactive rendering. But overall it looks fine. I am not opposed to closing this bug.
