»crop frame« – do you mean the Canvas?
Have you set Border to »None«?
Isn't that a stroke, an outline, a frame? A canvas is a material.
I was referring to the Canvas of the image (its complete rectangular area) – as in Image > Canvas Size.
Edit: And the OP seems to have set its »Border« to be indicated by a »Drop Shadow«.
Thank you for your answer. If i'm don't want border how can i'm setup interface.
Have you set the Border to »None« (Photoshop > Preferences > Interface)?
