Renders inconsistent from nodes

I am having a problem where on the final render you can clearly see the squares each node rendered in, like a chessboard effect This is a problem.

Please see attachment of close up of one section

Hello,

Which shader are you using on the surface where there are squares ?
Because, we found out that shader using random value in there settings do not look the same if they are rendered on Mac or Windows…
So if you are using a shader using random value, like the grass for example, you should only use nodes on the same platform, i.e.: all Macs or all Windows.
We hopefully will fix this issue in the next release.

Best regards,
