23.0.60; Poor font rendering example

1. Using the xft font backend, I start Emacs like this:
   emacs -Q -fn "-b&h-Luxi Sans-normal-normal-normal-*-12-*-*-*-*-0-iso8859-1" test.txt

2. I type M-: (insert (propertize "I think this is poor rendering of `i'" 'face '(:weight bold :height 1.2)))

This is the result I get:

Note the lower-case i's look like the upper case I.  If I increase or
decrease the size by face-remapping, the lower case i's look like they
should. (I use b&h-Luxi Sans for variable-pitch face, which with the
above face attributes defines info-title-3, which is how I noticed
this rendering problem.)

Please tell me from where I can get that font.

I'll email what I believe to be the right file to you off list.  It came
with openSUSE 10.3, I believe it's in the xorg-x11-fonts package.  You
can get the compiled rpm here:

http://download.opensuse.org/repositories/openSUSE:/10.3/standard/noarch/xorg-x11-fonts-7.2-85.noarch.rpm

and the source rpm here:

http://download.opensuse.org/repositories/openSUSE:/10.3/standard/src/xorg-x11-fonts-7.2-85.src.rpm

I believe the file is luxisr.ttf.

With the fonts you sent me, I confirmed that bad rendering
with the pixelsize 14.  But, the same rendering problem
occurs in gedit's font selection window (see the attached
image).  So, I think it's a problem of font itself or of
freetype library.

Ah, yes I see that here too.  Sorry it didn't occur to me to check
outside of Emacs before wasting your time and list bandwidth.  But
thanks for confirming the problem, and that it's not an Emacs problem.
I'll check the Xorg bug tracker.
