The Neirest Neighbor interpolation problem (after PS update)

Hello,
After my Photoshop CS6 update I have problem with the Nearest Neighbor interpolation. It was working correctly before, in 13.0 Photoshop release. (In previous PS versions, like CS5.5 it was not, so I was very happy to see this function working great in PS CS6). I still have this very first version of CS6 installed on my second computer and I don't have any problems wit that. As usual, I am setting the General and Free Transform preferences first to the Neirest Neighbor interpolation method and rotate pictures by 45 degrees then. It was always giving me pixel-perfect results, without any mess, in PS CS6 13.0. After update that stopped working (on the left: before rotation, on the right: the same object rotated by 45 degrees in the Nearest Neighbor interpolation mode):



Am I missing something? I have made video showing my results in updated PS version and all the steps I am making:

How about you? What are your results after rotating any picture by 45 degrees in the Nearest Neighbor interpolation mode? I would be happy to know what is wrong now and how to achieve good results as before. I will appreciate any help, it is very important to me.

I'm not seeing the problem with PS CS6 13.0.1. Can you post the file to YouSendit or other site?

I can reproduce the issue on 13.0.1 and Mac OSX 10.6.8.
In a Smart Object a horizontal border rotated 45 ̇ will produce regular »steps«, the vertical one not so much with Image Interpolation set to Nearest Neighbor.

Thank you both for taking your time.

@Todd: You can download my file from Dropbox. I am very surprised that you are not seeing this problem in 13.0.1 version. The question is why? I guess you have some additional option turned on, but I have no idea what that could be. I would be extremely happy to know how to fix that.

@Christoph: I have exactly the same result with any random file or new shape now.

Using a smart object I can confirm the Nearest Neighbor Transform fault. You are correct, it appears to be bug with 13.0.1.



It also happens with standard raster images (i.e. non-Smart Objects).
