new generated layer that is slightly misaligned

Hi everyone,
I’m having a recurring issue with Photoshop’s Generative Fill when using the Gemini 2.5 (Nano Banana) model.
Every time I apply a generative fill on a selected area — even for very small changes (like color adjustments or replacing a detail) — Photoshop creates a new generated layer that is slightly misaligned, either scaled differently or shifted by a few pixels, so the generated content doesn’t match the original position.
You can see it clearly in the screenshot:
– the mask is correct
– the selection is correct
– but the generated result appears on a layer that is not aligned with the original image
– this makes the output unusable, especially for precise work
I’ve tested:
– different files
– different resolutions
– different GPU/CPU settings
– stable vs beta versions
– resetting preferences
The issue persists only with Nano Banana, not with the other models.
Is this a known bug?
Is there a workaround to force the generated layer to match the exact scale and position of the selected area? Thanks in advance — this is slowing down my workflow a lot.
