Picture on surface get smaller than before

There is some option i use to do and seems impossible now:
On a surface, i put a photo, from my iPhoto library.
I draw with a curve the detail i want to keep,
I cut the surface with this curve,
now the surface should limits the picture of my face.
But with this version, the picture get smaller and my face is not in the full surface.
Is there a possibility to repair this?

This was a bug in the Windows version that was fixed recently. Since the Mac version is based on a somewhat earlier the Windows version (one or two service releases behind), it’s probably still in there. I assume it will get automatically fixed in one of the future Mac updates as soon as those catch up to the version of Windows where the bug was fixed…
