You can downgrade your Unity and Compiz to older version this may help https://askubuntu.com/questions/59443/how-can-i-revert-back-from-an-upgrade-to-the-proposed-repository
and don't forget to hold your unity version sudo apt-mark hold unity then you can upgrade to newest again(except unity and compiz). Another way is cancel this patch https://launchpad.net/ubuntu/+source/unity/7.5.0+17.04.20161130-0ubuntu1 and build a new package.I tried ,but fail.
