Font rendering is different when using -multiwindow

[Matt D.]

To add some additional information, I am having the font rendering issue 
when connecting my X session to a remote CentOS 6.4 machine. I cannot 
duplicate the issue when running applications locally through Cygwin.

I'm having some trouble narrowing this down but here are the results of 
my tests:

Remote X font rendering changed:
gedit 2.28.4 (Consolas)
gedit 2.28.4 (DejaVu Sans Mono)
Eclipse 4.2 (Consolas)
gtk-demo (GTK2)

Local font rendering unchanged:
gedit 3.6.2 (Consolas)
gtk3-widget-factory
gtk-demo (GTK2)

I don't have any good candidates to test this with, as I'm only familiar 
with gtk applications.

Attached are the results from xdpyinfo.
