This regressive behavior is well known. F13 has not been released, so it's
betaware. If you can't deal with bugs then don't replace what's working OK
with development versions. Newer isn't always better. If it's working, don't
try to "fix" it by "upgrading" to betaware. Meanwhile, someone must install
the betaware to find the bugs. If you think your experience is unique, report
in the appropriate manner. Did you look in bugs.freedesktop.org and/or
bugzilla.redhat.com before installing F13 or comming here? Complaining here
about a "big regression" is unlikely to be much help in getting it fixed.
