This is a false warning. There are known issues with the rows in the geometry 
given to Emacs (you may get less rows than you ask for) but the positions are 
AFAIK more or less correct (i.e. both Gtk and the window manager modifyes it in 
an effort to keep the window onscreen).  I don't know why they added this 
warning in Gtk+ 3, the code is more or less the same as in Gtk+2.

Now, if you have a case where the window position is much different from the 
geometry given, that would be a real bug.
