Not sure I understand. You mean you have enabled lens profile correction to get rid of the vignetting, but if you pull the shadows slider down you get the vignetting back?

Yes, Shadows and Blacks.  It is most noticable when you lower Blacks and then tweak the Shadows in either direction.

Cannot reproduce.

 

If I remove vignetting completely (slider set to 100), Blacks darken the whole frame equally.

 

Can you post a more formal bug report with step by step instruction to reproduce. Also, please post your lens and camera model.

A flat light shot illustrates this best (and Seattle has no shortage of them). This was taken with a Nikon D700 and 400mm f2.8 lens. The first image is without lens correction, and the next one is with.  You should be able to notice the auto-correction (which is not perfect but is close enough for this example):

Uncorrected:

Corrected

The next two shows what happens when you use the shadow control in either direction with lens correction in place:

This one begins to revert back to uncorrected with -Shadows.  (notice the dark tunnel)

This one is very obvious and appears uncorrected in the opposite direction with +Shadows.  The lens correction is essentially ignored, and in fact (I think) exaggerated upon.

In the above two you can clearly see the lens correction incorrectly influencing the way the new shadows and blacks controls behave. The 2012 controls are treating the lens correction like part of the image, and are not compensating for it. You cannot get a corrected image in contrast this way --fix the edge and the center goes off.  This is obviously going to be more noticeable with full-frame cameras in flat lighting situations.

For reference purposes I've included the next two images in 2010 process.  As you can see 2010 takes into account the lens correction, and appears much more even, and in fact, only as inaccurate as the lens correction itself:

I have also tested this with another lens to rule out the profile as the source. My whole point is that the lens correction should supercede any other image adjustments so as not to become part of the image.  I tend to think this is a bug, or at least I don't see how it could be "as designed".
