This is IMO rather a Qt bug as the reason for the crash is that in https://github.com/qt/qtwayland/blob/v5.9.1/src/hardwareintegration/client/wayland-egl/qwaylandeglwindow.cpp#L136 object() returns nullptr.
I'm not sure if that's the full reason. In thread 1 we'll see a window being destructed, so it's doing a final call to the render thread to delete things, but that's ending up doing a full on (now broken) full frame swap.
