I changed the affected package from cairo-clock to compiz, because I think that I get the same sort of behavior in other settings. For example, run Firefox and open a flash movie; then switch users.
Instead of switching users, you can also get the same behavior by doing Ctl-Alt-F1 to get to a new tty. Running top in the new tty then shows compiz using a large share of CPU, if there is an application running such as cairo-clock or a flash video in compiz. ** Changed in: compiz (Ubuntu) Sourcepackagename: cairo-clock => compiz -- High CPU when on another user's desktop https://bugs.launchpad.net/bugs/270880 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
