Hi Could you please install the Qt4 debug symbols (libqt4-dbg) and then submit a bug report on https://bugs.kde.org/enter_bug.cgi?format=guided against the 'kwin' product.
If you're running KDE SC < 4.12 . I would recommend upgrading to KDE SC 4.12.1 via the Kubuntu Backports PPA ( https://launchpad.net/~kubuntu- ppa/+archive/backports ) , reproducing the bug and reporting the bug on the KDE Bug tracker with appropriate backtraces. ** Changed in: kde-workspace (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1272438 Title: kwin 100% of cpu, second session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/1272438/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
