I just discovered that for me Emphaty is causing at least part of the problem.
After startup I see Compiz at around 1-2% cpu while doing nothing. And then I start Emphaty and now Compiz consumes around 15-16% of cpu. I then disabled the "People nearby" which did not seem to ever "connect" and voilĂ , Compiz is back at consuming only 1-2%cpu!!! This change also had the benefit that the ever spinning "trying to connect" indicator on the right of the availability dropdown only shows when I am actually connecting. However, it remains to see if this also stops the slowly increasing of cpu cycles for Compiz that I have seen previously. After a couple of days I have seen Compiz consuming up to 35% of cpu, but maybe this has been a consequence of the Emphaty problem. I will report again regarding how Compiz behaves after a couple of days. -- 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
