1.8.7 horizontal line over the image, image pushed together

I'm not sure if the additional problem was missed due to closing of the original thread, so I'm opening up a new one and link to it. I did also open a thread previously in the 'Reproduced - TODO' category over a week ago, with no traction so far. So I'm creating this new thread for visibility.

Version 1.8.7 improved on Lanczos4 and seems to be fixed, bilinear still looks blurry, but maybe that's just the nature of it. So far Lanczos seems to work fine so I'll go with it. But If I use Lanczos4 for 'Zoom in' in this version, there is a subtle image shift happening just about a pixel which pushes the image together and creates a horizontal line over the image.

It's easy to spot on the feet on the right panel, running all over the face/nose part and the text of the image to the left. Basically the top and bottom parts of the image get smushed together and create this line.

sorry but your links are not valid

They are still functional in the closed thread. By copy-pasting the links from the closed thread they got cut off midway.

In the original thread user0 also could reproduce the bug, the dropbox links are still working.
