Some sniffing (does Nux have any documentation? I couldn't find anything more than some doxygen-formatted comments) resulted in a find: Nux has GetGeometry(), GetRootGeometry() and GetAbsoluteGeometry() methods. I think using one of the latter two (and what's the difference? Doxygen comments were not clear enough) might fix the bug.
