https://bugzilla.redhat.com/show_bug.cgi?id=1477191 Currently on Win10 when one of multiple displays is disconnected by the client, the qxl-wddm-dod driver does not receive any update, the system just stops using this adapter for rendering. As a result, the 'disconnected' state of the adapter is not saved anywhere. On further connect the client side recognize the adapter as active and opens window for it. Current commit fixes the problem by sending QXL_ESCAPE_MONITOR_CONFIG with zero area to disabled adapter.
