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.
