Comment 2 Jared Smith 2015-06-27 06:18:39 UTC

I have built a patch for this issue, roughly based on the patch that OpenSuSE submitted upstream at http://mail.directfb.org/pipermail/directfb-dev/2015-March/006879.html, but has so far been ignored by upstream.

I'll submit this update to updates-testing shortly.
