Bug Description

I did nothing specifically. Suddenly most things were frozen. I could still move the mouse and also move windows around but most clicks were ignored. Clicking on the close-button gave me visual feedback but did nothing. After switching to tty1 and back, all windows became blank.

This is all the time I start KDE, mostly after starting any application (like Dolphin or KDE settings).

I recognized that there were some messages in syslog which might be related. Here with some context:

Of three systems I upgraded to 13.10 and KDE 4.11, I notice this only on my laptop, an X1 Carbon. It seems worse when the WiFi network connection is unstable or on restoring from suspend. After doing some research for similar symptoms, I removed every plasmoid from my desktop, which seemed to help but not eliminate the problem. If I "killall plasma-desktop && plasma-desktop", it starts working again for a while.
