Abstract: A user interface (UI) is displayed on a display coupled to an electronic device. The UI includes a first area of the UI visible on the display. A non-visible UI element corresponding to a second area of the UI that may be displayed in response to a user input on the electronic device is determined. An image of the non-visible UI element is drawn into a tile in a tile layer that provides a non-visible representation of views associated with the UI, the tile layer stored in a temporary memory area. The image drawn into the tile in the tile layer is compressed. In response to a user input on the electronic device, a representation of the second area of the UI is displayed on the display including the compressed image.

Abstract: A background thread can be used to process events, e.g., a touch, gesture, pinch, or swipe, that are received on a touch sensitive device, or events, e.g., mouse scroll wheel events that are received on a input device, e.g., a mouse. The background thread can be used to process events when a main thread assigned to the Graphical User Interface (GUI) is interrupted. In such situations, the background thread can continue processing events. In cases where the main thread is interrupted and the event is scroll input, the background thread can draw content on the GUI in response to the scroll, so that the response to the scroll input observed by the user is unaffected by the interrupted main thread. By processing events and drawing content using the background thread while the main thread is blocked, the GUI can be navigated without having the user experience a stall or stutter.
