Bug Description
If I enable Xinerama to create a desktop spanning 3 screens on 2 adapters, X will start correctly and become either unresponsive or crash after about 30 seconds. Everything runs stable w/o Xinerama, with the window manager only handling the center display.
Moving the cursor out of the first screen makes it flicker strangely and become stuck and/or invisible after a short time (1-2 seconds).

Further testing suggests that the error is only triggered by moving the mouse out of the first screen. Also it isn't possible to move it back to the first screen: the cursor flickers and is briefly displayed back on the main display then it is flickering again on the adjacent one.
Afterwards, pressing a key on the keyboard seems to shutdown X.
