PS CC horizontal and vertical lines appear in an images after using the straighten crop tool, very noticeable on darker, plain backgrounds. Also when straightening a smart object then zooming in to 100% the image 'corrupts' and digitizes in appearance.

Robert, I am experiencing what sounds like the exact same issue. This is the first I've found of someone else experiencing such a strange issue. Did you find out anything more in the past year? I've attached an image of what I'm experiencing...

That looks a lot like an old video card driver bug that amplifies the low bits of 16 bit/channel images. But I don't recall seeing that bug on MacOS before, only Windows - and driver updates fixed it.
