Seems to me some widget is going mad and constantly triggers redrawing. So we ought to find out which widget it is.... easiest way would be to backup .kde/share/config/plasma* and then keep removing widgets until the load turns normal.
should that not yield results you can also attach aforementioned files to the bug report and completely remove them, then restart plasma- desktop to see if it is a widget problem at all. also ls -l ~/.kde/share/apps/plasma/plasmoids/ would be good to see. ** Changed in: kde-workspace (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1173521 Title: plasma-desktop burning 90-100% of a cpu (after update to raring) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/1173521/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
