Public bug reported: I left X session, after some inactivity screenlock was displayed, it hapened when I was disconnected from my laptop using KVM switch. When I connected back to the laptop screen was corrupted as shown on the attached screenshot.
It never happened in Ubuntu 12.10. I managed to "repair" it by switching to the console and back.
