Comment 2 Ngo Than 2002-07-16 18:56:42 UTC 
Owen, i think it should be a bug in fontconfig?
Comment 3 Owen Taylor 2002-07-16 20:18:26 UTC 
Almost certainly a bug in the Qt patch for Xft, not in fontconfig.

I can't reproduce the problem here ... do we have any idea of which
fonts it is that trigger the problem?
Comment 4 Fortepianissimo 2002-07-17 04:02:14 UTC 
It didn't seem to be specific to a particular font; but for the snapshot it's
Microsoft Verdana.

This happened in other KDE applications as well, e.g., konqueror, kmail, etc.

BTW these are the relevant packages I installed:

fontconfig-0.0.1.020626.1517-3
Xft-1.9.1.020708.0036-2
freetype-2.1.2-4
qt-Xt-3.0.4-10
qt-MySQL-3.0.4-10
qt-3.0.4-10
qt-ODBC-3.0.4-10
qt-devel-3.0.4-10
qt-PostgreSQL-3.0.4-10
qt-designer-3.0.4-10

These packages were all rebuilt from SRPMS using
-O6 -march=i686
Comment 5 Owen Taylor 2002-07-23 16:50:35 UTC 
OK - I tracked this down a bit - it appears that the problem
is that Xft does this when it tries to make a bitmap font
articially italic. And *ALL* fonts in KDE are ending up as 
one bitmap font - the "LucidaTypewriter" font from the
bitmap-fonts package.

Comment 7 Owen Taylor 2002-07-23 18:47:24 UTC 
The fonts-at-an-angle problem is fixed with a patch extracted
from freetype CVS in freetype-2.1.2-5 (currently building). 
Now, we just need to figure out why all the fonts are 
LucidaTypewriter.
Comment 8 Owen Taylor 2002-07-23 20:13:57 UTC 
OK, I have a qt fix now ... it seems to be the 

 sample.unicode() != 0

issue again. Building a new qt on my machine to test
the fix.
Comment 9 Owen Taylor 2002-07-23 21:07:40 UTC 
qt-3.0.5-3 (now building) fixes these issues; main remaining Qt
font issue is the font listing not listing the right things.
Comment 10 Fortepianissimo 2002-07-26 02:12:26 UTC 
This is to confirm that

freetype-2.1.2-5
qt-3.0.5-3

together fixed the problems. Thanks guys!

Closing out as user confirms fix.
