It's a consistent thing I am seeing when generating things like "new hair color" or altering anything about the image I am working with - the new generation is great, but is almost always different size from the original image, either stretched a little bit, or squished, or larger, or shifted in space, but never exactly perfectly blended with the original image - so it takes a bit of effort to blend the new generation back into the original image.
Seems like a bug vs. a feature to me 🙂

i'm having an issue using the "nano banana" model with Generate Fill in Photoshop Beta.

When I generate with a selection that covers the entire image, it works fine and uses the reference photo.

But when I generate using only part of the image (for example, a small selection), the returned result is smaller than the selected area, although the content matches the reference photo. It creates a new layer with the result at a much smaller size and lower resolution. I understand the resolution may be lower than a high‑resolution source, but unlike Firefly it does not produce the result at the exact size of the selection, and I have to manually scale it up using Transform.
