Comment 128 for bug 1308105

The XFCE4's maintainer claimed to have merged the patch for this bug here: on 2016-08-12.

A new version of xfce-settings (4.12.1) has been released on 2016-09-15 so we can assume that the fix is integrated in the release.

Note that the patch is not the same as the one I've linked in comment #107. I still have to test the new version.

Note also that the 4.12.1 version was not integrated in ubuntu 16.10 so we still have to recompile and install it manually :(
