                   |             |
                   +-------------+

Choose rectangular area capture
Select from left monitor which is not aligned with others

Result: wrong part of the screen is captured. 
It's only working ok when top and left monitors are aligned.

Capturing in top and laptop monitors are ok.
In previous versions of spectacle it worked ok.
