This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.

More information and reason for this action is here:

Comment 10 Pravin Satpute 2010-10-13 06:47:43 UTC
can we get steps to reproduce this bug?

Comment 11 Misha Shnurapet 2010-10-13 07:11:54 UTC
These are contained in the bug report, but to make it clear:

1. Install the font rendering libraries with the patented technologies enabled (using the repository from infinality.net, config provided)
2. Use the .fonts.conf provided;
2. Install Liberation fonts and set them as the system default typeface, set its size 8 points.

Comment 12 Pravin Satpute 2010-10-13 07:22:36 UTC

Comment 13 Akira TAGOH 2011-12-05 11:15:39 UTC
Pravin, any updates on this?

Comment 14 Pravin Satpute 2011-12-07 10:38:47 UTC
not yet. next month i will go through this bug.

Comment 15 Pravin Satpute 2011-12-19 16:15:49 UTC
Hi Misha and Caius

  while digging on it, i found that when we enable auto-hinting at 8pt size this problem is happening.

  
 $ftstring  -r 96 -m 6б8 ppem 200 /usr/share/fonts/liberation/LiberationSans-Regular.ttf

 press up arrow and make point size 8pt, press f for autohint on-off, observ behaviour

 ftstring is part of freetype-demos package

  from Fedora 15 onwards we are using bytecode interpreter hinting, so i think problem should not occur now.

  can you check this once?

Comment 16 Pravin Satpute 2012-10-05 05:49:41 UTC
can you test this with the latest version of liberation fonts 2.00.1?

to me again this happens only when we enable auto-hinting but we are not using it for liberation font in Fedora

Comment 18 Fedora End Of Life 2013-01-17 02:03:08 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 19 Pravin Satpute 2013-01-21 06:49:39 UTC
hmm, since we switched backed to liberation 1.0 this again need some work.

Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.
