Try to login with a fresh new account. If the problem persists, it might be 
due to the kwin compositor not liking your graphics driver. In that case, you 
might try to disable compositing (set "OpenGLIsUnsafe" to true in your 
~/.kde4/share/config/kwinrc) and restart KDE. If that works, you might try to 
change some advanced options in the Desktop Effects settings (e.g., try to 
disable "Use OpenGL 2 Shaders") and try to re-enable compositing. You might 
also consider to file a bug upstream.
