I'd hope not; I use the tty version of top so it is supposed to update only the window content not the window decoration. I had already disabled all thumbnail generation I could find when I did a previous hunt for kwin "hoggers". BTW, even with a top refresh interval of 10s kwin keeps showing up so indeed something else is going on.

My clock ("Digital Clock") is set not to show seconds and I'm not running any auto-updating widgets other than the battery monitor (on the desktop, not in a panel) and the telepathy thingy. I have a top and a bottom panel though, both of which can be covered by regular windows. But that's a feature that should be event-driving, iow not take up cycles when I'm idle.
