Short description of error
While trying to key green screen if my viewer node is on the second monitor it always picks up black color. I have to sample the color within the same monitor to make it work.

You need two monitors to test it.
Open two windows, one NODE EDITOR, the other UV/IMAGE EDITOR.
Drag one of them to the other monitor
