Blender Version
Broken: 2.79 & 2.79b & blender-2.79.0-git.26ee700-windows64
Worked: unknown

When rendering file to be tiled, the items at the top and bottom don't match without a significant offset.

The top 'ribbon cable' is skewed to the left about half a 'wire', you can see the other 'ribbon cable' at the bottom when you zoom out.

To verify, hide the guide plane on layer 2, hit f12, save the image and open in gimp. Layer > transform > offset > click offset by x button > click offset button
(you can actually tile the image with; filters > map > tile > set the image to at least 4000x4000 )
The ribbons will match, despite being purposely misaligned in blender.

Respectively, when you align the cables, as they should be, they do not match when tiled. Just show the guide and move the top ribbon cable over about half a wire to fit within the guide and re-render. The board traces do seem to match, but the ribbon cable does not.

Strange, no?

Thanks everyone!

Thats because you are looking at subdivision level 1 in the viewport and rendering happens with subdivision level 2

Both Rbbon Cables are not aligned (and might subsurf a little differently depending on the underlying geometry), so if you want to make sure you are looking at the same thing as your rendering in the viewport, you have to set View and Render to the same level in the subsurf modifier.

No bug here that I can think of.

I'm guessing you meant the cable arrays are not aligned on the same side (say both starting on the left) while using subdivide. Instead one was rotated 180, thus they shrink towards the main item in the array and don't match up at render. I was sort of thinking this after I posted it.

(for future reference)
This can be solved by either using a constant offset in the array and/or setting your arrays to start on the same side of the screen.

Thanks Phillipp!
