This sounds more like a problem with fglrx, are you using the one from 
ELrepo?  I'm still on FF 10ESR here, but under Options/Preferences (they 
keep changing it I swear!), in the advanced section, general tab, you 
can uncheck hardware acceleration.  See if that alleviates the problem. 
  It may be useful to check your Xorg log files for clues as well.
