When waylandsink is used on some other thread than the main wayland client thread, the waylandsink implementation is vulnerable to a condition related to registry and surface events which handled in seperated event queue. The race that may happen is that after a proxy is created, but before the queue is set, events meant to be emitted via the yet to set queue may already have been queued on the wrong queue. Wayland 1.11 introduced new API that allows creating a proxy wrappper which can help to avoid this race condition.
