Description cje 2009-04-15 00:01:17 UTC
Description of problem:
in the default font and size used in firstboot the '5' digit is a slightly different width, i think.  so in the 'date and time' settings screen the text shuffles a bit as the seconds and minutes tick through 05/15/25 etc.

ah, actually, it looks like it's a hinting problem - this happens with 'full' and 'medium' but not with 'slight' or 'none'.  not sure if that means it's a problem with freetype rather than the font.

Version-Release number of selected component (if applicable):
freetype-2.3.9-3.fc11.i586
dejavu-sans-fonts-2.29-2.fc11.noarch

How reproducible:
always.

Steps to Reproduce:
1.install fedora
2.in firstboot go to date&time screen
3.watch the time ticking and observe text layout

alternatively log in and enable seconds display and 12 hour mode on the panel clock and watch that.
  
Actual results:
layout 'jiggles' as numbers change.

Expected results:
no jiggling.

Additional info:
i think this has been like this for a year at least.

Comment 1 Nicolas Mailhot 2009-04-15 07:31:08 UTC
If it happens only with some autohinter settings it's clearly an autohinter bug.

Please file a report in the freetype component of freedesktop bugzilla (CC-ing fedora-fonts-bugs-list at redhat.com)

Comment 2 cje 2009-04-15 12:41:17 UTC
okay, i will do that.  but are you certain that it _must_ be the freetype autohinter?  aren't some of the hinting things stored in the fonts themselves?  i did try a couple of other fonts and couldn't reproduce the same behaviour.

Comment 3 cje 2009-04-15 12:57:21 UTC
freetype bug raised.  :-)

Comment 4 Kevin Kofler 2009-04-15 12:58:11 UTC
The Fedora freetype package is built without the interpreter for hinting bytecode for patent reasons, so yes, if you're using the Fedora freetype package, it must be the autohinter.

Comment 5 cje 2009-04-15 13:02:08 UTC
ah, right.  thanks for the explanation.  makes sense.

Comment 6 Bug Zapper 2009-06-09 13:50:36 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Comment 7 Bug Zapper 2010-04-27 13:41:13 UTC
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  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bug reports from releases that are no longer maintained.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 '11'.

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 11'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 11 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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 8 Bug Zapper 2010-06-28 11:50:25 UTC
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.

Thank you for reporting this bug and we are sorry it could not be fixed.
