[K12OSN] Adobe Flash graphics-corruption in K12LTSP for web-based program

[Jim Kathan]

Thanks guys. For those who missed the previous posts about this, the "missing text" problem is a known and common bug with Flash in Fedora, and should be fixed internally in the upcoming version 9. My research found this:

http://macromedia.mplug.org/faq.html

specifically #11:

Fedora Specific Information 
------------------------
11. Most text is failing to display on Flash sites!

   The plugin has bugs where it makes bad assumptions about the font configuration.
   For this reason, it fails to find fonts on newer versions of X.org.  You can 
   workaround this problem in the short-term by using these commands as root.
   
       mkdir -p /usr/X11R6/lib/X11/fs/
       ln -s /etc/X11/fs/config /usr/X11R6/lib/X11/fs/config
   
   Read Red Hat Bugzilla #184028 for more information about this problem.
   Adobe should be fixing this in Flash version 9 for Linux.

and here's the subsequent link:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=184028

it now displays fine and all is well!
