[Bug 744812] Re: FontConfig/Qt stack choke on Ubuntu Medium font meta-data (No medium in Inkscape and too bold in Qt apps)

[Björn Michaelsen]

Also note that any nontrivial patch there will affect all fonts in
rendered documents opening us to a lot of havoc, if our vendor patch
makes documents being rendered different (different font weight might
change pagebreaks, thus numbers of pages, manual (hardcoded) references
to pages or images -- esp. things like "last page") on Ubuntu than
everywhere else (Windows, OSX). Even if we would do it right, and
everyone else would do it work -- the users likely would not care, if it
destroys their crossplatform document fidelity (with the same major --
even minor).

Bug description:
  [Kubuntu natty up-to-date]
  Hi,
  Without any change on my system, I noticed some days ago that my default font (ubuntu) changed. Some odd behaviour appeared : ubuntu medium 10 pt was ok but ubuntu medium 11pt was bold (-> in my taskbar clock or in kpackapgekit). In fact, after some play with kcm kubuntu font manager, the ubuntu medium 10pt was wrong, since kcm module shows the true appearance of ubuntu medium, which is quite bold. I swapped to ubunu light font
  SO ! I changed font hinting to light (default in kubuntu seems to be medium) and it seems to have solved bugs.
  Anyway, "ubuntu font" management by KDE seems to be strange, and firefox 4 font rendering is worse (imho) with light hinting (but maybe because of unselected "system default" parameter in fonts kcm).
