P: PDF import show edge artifacts on tiled PDF images (bug in PDF creation)

When importing a PDF with images, Photoshop CS6 adds faint outlines to the PDF image segments in the file. Prior versions of Photoshop render the PDF correctly. See the attached image for an example.

    Yes, this appears to be a bug in the PDF/EPS rasterization engine.
    Can you send me a copy of that PDF so we have a good example of the problem?

    Yes, same problem here. It seems to be importing the atomic regions between flattened transparent elements that are visible in Acrobat when screen optimisation is turned on, but are strictly as I understand it an anomaly of viewing the PDFs on-screen. It used to be the case in CS5 that they weren't rendered when imported into Photoshop, but now they are.

    However, you can get avoid the white lines if you turn off anti-aliasing in the Import PDF dialog. Although, then, of course, the imported image isn't anti-aliased.
