Comment 6 for bug 382843

Yes, I too am using Gnome-Do in Docky mode. I discovered this while switching on and off Compiz to test composit mode with metacity itself. When disabling composite effects, I noticed the bottom side of my screen turned black until metacity kicks in. The black part of the screen is related to the screenspace that Gnome-Do claims for its own.

Changing package hint to Gnome-Do. Either Gnome-Do should take less screen space, or find another way to keep drag and drop functionality.
