I think this bug has become confused. Compiz using high CPU when the screen is idle is definitely a bug and should be what this bug is all about. But using higher CPU than idle while moving windows or playing video are not unusual, because compiz is the process responsible for rendering EVERY pixel on your screen. Compiz is the compositor for Unity.
That said, I did create an experimental optimization for the compiz "move" plugin the other day that more than halved the CPU while moving windows. It's still experimental. Please test my PPAs which contain proposed performance enhancements for compiz and unity. Generally the Unity plugin is the largest contributor to compiz' CPU... ppa:vanvugt/compiz | https://launchpad.net/~vanvugt/+archive/compiz ppa:vanvugt/unity | https://launchpad.net/~vanvugt/+archive/unity ** Also affects: compiz-core Importance: Undecided Status: New ** Also affects: compiz (Ubuntu) Importance: Undecided Status: New ** Changed in: compiz-core Status: New => Confirmed ** Changed in: compiz (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/803943 Title: compiz consuming a lot of cpu To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/803943/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
