Bug#745875: /usr/bin/kwin: KWin consumes 100% of one of my CPUs while idle
Hello. I recently discovered that the screen lock under control panel's Screen and Monitor section was enabled, and after I disabled it my CPU consumption is back to normal. I guess the scren lock feature is somehow related to this bug. ¡Hola Marc!
