We have already located the bug and there is a fix in xorg-x11-server's
git repository.

http://gitweb.freedesktop.org/?p=xorg/xserver.git;a=commitdiff;h=649e7f82d8d4333443493056b81eb20d6cf022bc

I also have a bug opened in redhat's bugzilla for inclusion of this
patch

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=241214

I would suggest that you bother your distro to also include it.
