Version: (using KDE 4.2.2) OS: Linux Installed from: SuSE RPMs This was originally reported downstream here: https://bugzilla.novell.com/489990 When locked the calendar widget causes plasma to use 100% of the cpu. 1. unlock the desktop 2. click "add widgets..." 3. add calendar on the desktop The CPU usage stays low near 0%. 4. lock the widgets The CPU usage jumps to 100% only after locking the widgets. 5. unlock the desktop again The CPU usage stays at 100%. 6. remove calendar The CPU usage goes down close to 0%.
I can confirm this behavior using kde 4.2.2 archlinux packages.
Marking as duplicate of bug 187699 as the situation is related (calendar on desktop, changing properties -> 100%Plasma,Usage, removing it fixes the issue) Thanks for reporting *** This bug has been marked as a duplicate of bug 187699 ***
