Diagonal pixel shifting after auto-aligning layers

Question

After a photoshoot I used a series of six photos made from the same spot, which I wanted to auto-align, to make sure thay match, before I start masking out details I didn't like.

The auto-aligning worked absolutely perfect, until I started zooming in on one of the photos. I then noticed in five out of six photos a large amount of diagonal pixel shifting throughout the frame. Only the lowest layer wasn't affected by this pixel shifting.

Below a fragment of the base layer (not affected):

And this is the same fragment of one of the top layers, after the auto-align:

The shifting is clearly visible in the hard edges next to the orange arrows, and you can see the shifting goes through the entire frame..

I also attached the high-resolution screenshots.

After repeating the auto-align on the original layers I noticed the same results, so it's not a one-time error.

Anyone else ever experienced this?

Specs:

- Windows 11

- Photoshop 25.9.0

Hi Dave,

unfortunately this is not about nudging a layer to make it align perfectly with the underlying layer(s).

The second image in the orginal message is from one of the top layer, after auto-aligning, which creates a large series of diagonaly shifted pixels. Thus the shifting is caused by the 'Auto-align Layers'.
