The attached patch is the minimal patch making the rendering issue
disappear. Also, I cannot reproduce the issue when I try to configure
emacs just with ./configure --with-x-toolkit=lucid. The options I used
to compile emacs in my OS (I am using gentoo) are

./configure --prefix=/usr --build=x86_64-pc-linux-gnu
--host=x86_64-pc-linux-gnu --mandir=/usr/share/man
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc
