Screen mapped background & shift lens

If you map an image to the background via IBL and check Map to Screen, it of course maps your image to just the render portion of your window. But if you then use shift lens the background image "sticks" where it was in the viewport while your camera is moving. It still renders correctly however, but since your viewport doesn't match up with the render with regards to that background image it makes it very difficult to position everything correctly and predictably.

This is still an issue. Any chance of getting this fixed?

I think since the image is 'stuck' to the camera frame it would be difficult to make it work otherwise. A suggestion, I'd do all the camera matching without using shift lens first, then as a final step add shift lens and you can then use the Offset in IBL to line up the bottom of the screenmapped image with the bottom of the camera frame to see where it would be lined up when rendering. Then set the offset back to 0 for rendering.

What dictates that it must be 'stuck' to the camera though? Couldn't the shift lens adjust the background image in the same way and to the same degree which it shifts the lens? I like your work around. Really, with the realtime preview this will be even less of an issue. However, I'd still consider it a bug since not only are you not getting what you see (WYSIWYG) but it's suggesting you'll get one thing and then giving you another at render time.
