Short description of error
When two compositor windows are open on different monitors, interactions do not work as expected:
For example, when interacting with nodes, click and drag (move) doesnt work when on separate monitors, but when both windows live on the same monitor, the problem no longer exists (see video example).
Exact steps for others to reproduce the error
Open a compositor project, duplicate the blender (compositor) window, duplicate to a separate monitor and you can no longer click and drag nodes.
