I cannot reproduce this.  The settings in the init file, both the font
family and its size, get reflected in the default face's font for me.
But I'm not on an X/GTK-based system, so I suspect something like
xsettings or gsettings or somesuch are responsible for the resetting
of the default face's font.  Perhaps Po Lu could help.
