Description Roman Kagan 2011-09-14 12:38:12 UTC 
Description of problem:

LiberationMono Bold and Italic fonts have metrics different from Regular and BoldItalic.  This results in various artifacts, e.g. misaligned bold text in xterm or gnome-terminal at certain resolution and font size.

Version-Release number of selected component (if applicable):
liberation-mono-fonts-1.07.0-1.fc15.noarch

How reproducible:
100%

Steps to Reproduce:
1. using freetype-demos package:

# for f in /usr/share/fonts/liberation/LiberationMono-*; do
  ftdump $f | grep -e postscript -e ascent -e descent
done
   postscript: LiberationMono-BoldItalic
   ascent:          1705
   descent:         -615
   postscript: LiberationMono-Bold
   ascent:          1707
   descent:         -615
   postscript: LiberationMono-Italic
   ascent:          1707
   descent:         -615
   postscript: LiberationMono
   ascent:          1705
   descent:         -615

  
Actual results:

ascent for different styles is different.  As a result, at 106 dpi at size 10 pt the rounded ascent is different, too.  This makes bold characters misaligned in xterm and gnome-terminal (when used with freetype-2.4.6)

Expected results:

all metrics are the same

Additional info:

Full details are available in freetype bug https://savannah.nongnu.org/bugs/index.php?34156.

version 1.06 didn't have this problem.  It looks like it's due to the changes introduced to fix bug 591559.
