Having the same problem on a late-2013 Macbook Retina Pro running Ubuntu 17.04 Zesty and previous versions.
Seem to have got a fix with: 1 CCSM General - OpenGL - 'uncheck the "Sync to VBlank" option' and 2 CCSM Desktop - Ubuntu Unity Plugin - check Enable Low Graphics Mode -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293384 Title: Compiz CPU usage dramatically increased in Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1293384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
