I have a similar issue with scaling: I have *3* monitors, two side-by-side (primary & secondary) at 100% scaling, and a third above them that I normally run at 125%. When doing a capture of a region, the 125% can capture with fidelity, but the other two displays have their "as displayed" view scaled to 125%, cutting off the lower & side portions. It's like Screen Captor is telling Windows to statically grab the entire workspace, then displaying that across the three displays as a single 125%-scaled image. When I switch the third display to 100%, everything works as expected.
