It's obviously something to do with the graphic display, but it would seem to me to be using too much of the main CPU.
I have a quad core, 2.8GHz processor with 8Gb Ram, and no particularly graphics intensive software running (Kontact, Firefox, Amarok, gkrellm, Krusader). The graphics card is nVidia GeForce 9600GT.
I'm running openSUSE 11.3 and KDE 4.5. Sounds familiar...

This has been discussed a fair bit here on the mailing list with various solutions. The one that worked for me with all nVidia/openSUSE11.3 combinations was a kernel upgrade (and of course re-installing the nVidia binary driver)
C. Turning of KDE4's desktop effects (i.e. suspend compositing) will drop the CPU usage to near zero again. Consistently repeatable here but things are much better with the 256.44 drivers and 2.6.35.1-1 kernel. Still, if I want max

I did notice that switching off Blur (I *think* it was Blur, anyway) did make a significant difference in CPU usage. It might be worth switching off the desktop effects one-by-one to see if there is a consistently repeatable pattern. If there is, then a bug report is in order.
Same here on two machines - one with an NVIDIA card and another with an ATI card. I've reported this as an bug against KDE because the same Xorg/driver stack on both machines runs GNome + compiz without any issues. https://bugs.kde.org/show_bug.cgi?id=248729 -- Regards, Vadym ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
