I run a OpenSuse 12.3 x64 with KDE. A few days ago I played TuxRacer (LOL) and wantedn to minimize game. Somehow it didnt really work and on the desktop all Icons were gone. I did a restartd and it worked again. Now... Every time i start up Suse, all Icons are gone. On the right site of the desktop is a additional little scroll bar, but no matter how far i scroll, no icons. Only thing that works is clicking "Activities" and switch to "Desktop" and then back to "Destkop Icons". Then the Icons reappear and the scrollbar disappears.

Any idea whats wrong? This is really annyoing and I have no idea what happened. Please note: usually my desktop is "locked" so nothing can change.

Thanks for help.
