Comment (by tom):

 To add some explicit instructions here as this gets referenced often. For
 a built browser suffering from the problem, on Windows:

 1. Copy browser/omni.ja twice, once to omni.ja-backup and once to omni.zip
 2. Unzip the zip file using Windows built-in Zip Extractor. ([0] Indicates
 that other zip programs will not work correctly)
 3. In the extracted omni/ folder, edit default/preferences/firefox.js and
 add ``pref("gfx.direct2d.disabled",true);``
 4. Repackage the folder by running (in the extracted omni/ folder) ``zip
 -qr9XD omni.ja *`` - I used the cygwin zip package to do this. [0]
 indicates that other packaging methods will not work.
 5. move the repackages omni.ja over top the original (you have the back up
 right?!) and test!

 I was able to get it running with only gfx.direct2d.disabled - maybe one
 might need the layers.acceleration.disabled set to true too?
