I suspect that your problem may be with the "smoothScale" channels. Whilst I can't advise you on how to fix the smoothScale channels, you may get better results by just deleting them. If you want to try this, make a copy of the cr2 with a new name, use the free utility CR2Builder (or CR2 Editor, or a text editor) to delete the smoothScale channels from the eyes, head, neck, and any other parts that have scaling problems. I'm not sure what causes this problem, but it may be due to wrong rotation order when the cr2 is made.
