I'm using KDE 4.2.2 as a test. The problem occurs only if the composite manager is enabled. The problem occurs spontaneously when the new window is created. A reliable way to reproduce the problem - run concurrently several applications that create new windows. Typically, a window appears on the screen with some delay after starting the application. Time delays occur (drawing) of a new window depending on the application. The problem occurs if one or more applications have opened new windows (the window starts to draw on the screen) at about the same time. You can run fast (this is important) one after another "Konqueror", "System Settings", "File Manager", it is enough to reproduce the problem. The problem looks like this: X-server in "drmwtq" state. The screen freezes or just turns off. The keyboard sometimes works, sometimes not. I used a 9800 AGP at the UP and X550 PCI-E to the SMP AMD64 system.
