KDE 4: Ugly Icons in controll panel

Hey,

I’m using openSUSE 11.0 with newest KDE from KDE:Factory-repositories.
I like the KDE(4) integration in openSUSE very well, but I have a little issue with the running-programs-icons in the control panel.
When using a dark bar design the icon backgrounds are very ugly, just have a look at following screenshort:

Any hints how to make them look nicer?

Greetings

Note:
Restartet X.org, now the icons do look kind of fine (well, the icon background is a bit to dark for the panel, but at least it isn’t such a stupid redmond-g(r)ay anymore).

Regards
