Blurry images with distributed rendering

Hi, I’m writing to report a problem with distributed rendering.
Some parts of the image become blurry after the second render node finishes a couple of passes. Please see attached image. I already checked texture paths and everything is fine.
If I render with just one pc, the problem doesn’t appear. Can you please help me with this matter?
Thanks very much

Clearly there is some shift between the images contributed by different PCs. Are you using some plugins? Camera correction? Shift/tilt? It could be that the plugins is not installed on one (more) nodes.
