I certainly should have mentioned that my observations were made under 
the MAC OS X 10.10 (Yosemite) operating system.  I too have not been 
able to observe this problem under Linux (Ubuntu).  As Konstantin has 
pointed out, it does not seem possible to add a margin to the popup 
menuitem box in Linux to test if the problem would arise.  I will try to 
determine if the problem arises in the XQuartz X11 libraries or in the 
GTK3 libraries.  But the incorrect motion event data seems to point to 
the X11 libraries on the MAC.
