I have found the solution - with other hardware, but worked for me as well, so I marked as duplicate. Due to other hardware I do not have Catalyst Center, but alternative steps In OpenGL section sync to Vblank sign -> off (this made my CPU workload 70%) AND 4. Run "ccsm" (I had to install) 5. In Workarounds, enable "Force full screen redraw (buffer swap) on repaint". ... and reboot worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511727 Title: compiz HIGH CPU usage only during screen is off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1511727/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
