Downgrading is a good idea and may help during trouble-shooting.

Create a fresh user account and try to reproduce the problem there.

Become familiar with the Fedora Updates System website
running an app called "bodhi":

  https://admin.fedoraproject.org/updates/

Locate the update tickets that may be the culprit. In one ticket there
can be multiple packages. Perhaps you've not downgraded all related
packages. Also watch out for new test-updates that may already fix
the problem.

Finally, the links of the form

  http://bugz.fedoraproject.org/SOURCE-RPM-PACKAGE-NAME

    e.g. http://bugz.fedoraproject.org/eclipse-cdt

are a very convenient to Fedora bugzilla and other infrastructure
places, such as a list of currently open problem reports. It may be
necessary to open a ticket there, especially if you can reproduce
the problem in a fresh user account.
