When capturing a rectangular region Spectacle shades the screen obscuring the details needed to mark the start and end of the desired capture region. Changing the preferences, unselecting [ ] Use light background color, does not remove the shading, but makes the shading dark making it virtually impossible to see the screen at all on laptops.

There should be a way to completely disable this shading entirely as it makes it more difficult in many cases to select the desired rectangular region. ksnapshot worked perfectly without any shading allowing you to accurately capture the region of interest. The shading makes it impossible to determine where to start/stop a region when attempting to avoid parts of gradients, etc... forcing yet another import into gimp to clean up what should have been a simple screen grab.

I would include a screenshot showing the problem, but since spectacle can't even run a multiple instance -- that is impossible too. (frustrating, when ksnapshot had none of these issues)
