Perhaps your KWin doesn't have EGL support, so that workaround fails.

The proper solution is to upgrade to Mesa 10.0.5, 10.1.1, or 10.2-rc1.  That
will fix the actual driver bug.  If you upgrade to one of those releases, and
still experience the problem, please reopen the bug.

I also highly recommend upgrading to X server 1.15.1 or 1.14.6.  It isn't
strictly necessary, but without it, things will be slow.</pre>
