Several updates ago (version 2.8.2) I modified the automatic cropping logic so that it properly processes colors on pages. Before, it would just ignore pixels that should have been considered. If both of you went from 2.8.1 to version 2.8.7, then we can certainly discuss these changes, but otherwise, no other changes have been made to the automatic cropping.

Hallo Mike,

Thanks for the upcoming update and the bug-fix!
 
About the "sensitivity" of the Auto-Crop, I think that it should not be very high, since a scanned  document very often creates these dark pixels you mentioned.
I guess the possibility to set the sensitivity would be great.

I also provide you an example of how an original file (left) is being processed with the Auto-Crop (middle) and the Agressive-Auto-Crop (right) function.
As you can see the black, lined pixels on the bottom, prevent the App from cropping at all (too sensitive), and the agressive cropping is cutting half of the page away (too agressive).
