Summary:
Awesome bug.  

If you capture a Mail.app Reply window around 800-820 pixels wide with CGWindowListCreateImage kCGWindowImageNominalResolution you get a corrupted image (see attached).

If it's not a Mail Reply window, or its not around 800-820 pixels wide, or you don't use kCGWindowImageNominalResolution, then the bug does not surface.

I have a Retina iMac 5K with a non-Retina second screen on the right - this may or may not be relevant.
