I've investigated GIMP's https://bugzilla.gnome.org/show_bug.cgi?id=676708, on Windows XP, and the cause is that 'GetClipBox', on XP, for desktop's hdc returns NULLREGION and an empty rect. That produces an empty win32 surface which then, used as a source, paints nothing (do_nothing returns true).
With the attached patch GIMP's color dialog color picker returns the color under the pointer also on XP.
