I see the same behavior when I enabled visual effects. Not using "workspaces on a cube", just enabled "normal" visual effects. Had a configuration with 4 virtual desktops in one row in the workspace switcher and I can no longer drag and drop applications betweens the desktops. There is no problem in switching between desktops and opening new windows on it, though.
