Description Nikos Chantziaras 2009-12-03 02:21:17 UTC
I was hit by this for quite a while in KDE 4.3.3, and 4.3.4 didn't fix it:

It's a common bug but many people don't notice unless they monitor their CPU usage or temperature. The two following patches fix the problem:

4.3.5 is in portage now, is it worth backporting?

Not worth, 4.3.5 is our stable target.
Thanks for the patch anyway
