ZDI-CAN-19866/CVE-2023-1393 If a client explicitly destroys the compositor overlay window (aka COW), we would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. Make sure to clear the CompScreen pointer to the COW when the latter gets destroyed explicitly by the client.
