Description Michel Lind 2009-10-04 22:18:33 UTC 
Description of problem:
With both Adobe AIR and Adobe Reader, using the Droid Sans font as the application font causes rendering problems: all characters are rendered as rectangular boxes

Version-Release number of selected component (if applicable):
google-droid-sans-fonts-20090906-5.fc12.noarch
pango-1.26.0-1.fc12.x86_64
pango-1.26.0-1.fc12.i686

How reproducible:
Always

Steps to Reproduce:
1. Open GNOME Appearance Preferences
2. Set Application font to "Droid Sans"
3. Start acroread (RPM: AdobeReader_enu) or Adobe AIR installer (RPM: adobeair1.0)
   both are from Adobe's yum repository: http://linuxdownload.adobe.com/linux/i386/adobe-release-i386-1.0-1.noarch.rpm
  
Actual results:
Boxes. See screenshots

Expected results:
Should work fine. Note that using Droid Sans Mono and Droid Serif works perfectly.

Comment 3 Michel Lind 2009-10-04 22:51:29 UTC 
The Adobe AIR installer is actually here:
http://get.adobe.com/air/

It registers itself in RPMDB after installation, but is not part of Adobe's Yum repository -- yet.
Comment 4 Michel Lind 2009-10-04 23:14:12 UTC 
This problem, interestingly, does not occur on a 32-bit installation, only when running Adobe Reader (a 32-bit app) on a 64-bit install.
Comment 5 Behdad Esfahbod 2009-10-05 19:33:46 UTC 
Problem seems to be in either cairo-ft or freetype.  Need someone to debug, to see where the out-of-memory status is coming from.  I don't have access to a 64bit machine.
Comment 6 Michel Lind 2009-10-05 20:49:42 UTC 
Maddeningly, I cannot reproduce this anymore (it reliably occured yesterday). Feel free to close the bug.
Comment 7 Bug Zapper 2009-11-16 13:15:42 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.
