Sorry, totally wrong description. I just now observed that this CPU spike only happens when I have https://www.blogger.com/start (the German version) open in Firefox (2.0.0.10). I guess it's a Firefox <-> Xorg (<-> Compiz) problem. As I only opened this page after upgrading Compiz, this problem is most likely NOT related to Compiz at all.
** Also affects: firefox Importance: Undecided Status: New ** Also affects: xorg-server Importance: Undecided Status: New -- (hardy, xorg, compiz) xorg becoming temporarily unresponsive after latest compiz upgrade https://bugs.launchpad.net/bugs/180055 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
