OS: Opensuse 11.4 KDE. Installed from KDE LIVE CD.

The problem is, when running gtk apps, All apps has a ugly white box in top.
Picture told better than text,
pidgin and gimp,

geany ide,

monodevelop ide,

These all are gtk apps and have the same problem.

Taken steps,
1) Updated all gtk* packages (zypper update gtk*)
2) Reinstalled "oxygen-gtk" and "oxygen-icon-theme"

Have any idea how can i get rid of these boxes ?
