Abstract: A computing device may instantiate a light dismiss manager for an application user interface. The light dismiss manager receives a request to register an event pass area from a rendered user interface surface of the application user interface and receives a notification that a new light dismiss user interface surface is to be opened in the application user interface. The light dismiss manager determines a shape of a transparent blocking panel that excludes the event pass area. When the new light dismiss user interface surface is opened in the application user interface, the transparent blocking panel is rendered below the new light dismiss user interface surface. In response to an input event directed to a visible portion of the rendered user interface surface, the new light dismiss user interface is closed, and a command associated with the visible portion of the rendered user interface surface is executed.
