The PPA you linked has a compiz package with a version number less than the one on my system.
I used backportpackage to get the vivid version into a personal PPA for my utopic system and installed that. The issue persists. Here is my new apt-cache policy compiz: compiz: Installed: 1:0.9.12.0+15.04.20141219-0ubuntu1~ubuntu14.10.1~ppa1 Candidate: 1:0.9.12.0+15.04.20141219-0ubuntu1~ubuntu14.10.1~ppa1 Version table: *** 1:0.9.12.0+15.04.20141219-0ubuntu1~ubuntu14.10.1~ppa1 0 500 http://ppa.launchpad.net/andrewrk/misc/ubuntu/ utopic/main amd64 Packages 100 /var/lib/dpkg/status 1:0.9.12+14.10.20140918-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ utopic/main amd64 Packages -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415195 Title: OpenGL "hello world" windowed vsync app brings unity to its knees To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1415195/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
