Abstract: Techniques are described for generating image content for display. A host processor may read opacity information generated by processing circuitry for one or more blocks of pixels of a first layer of a plurality of layers. The host processor may determine an inner rectangular portion of the first layer that is substantially opaque based on the read opacity information, and instruct a display processor to not retrieve, for use in composing the plurality layer, an area of a second layer of the plurality of layers that is occluded by the inner rectangular portion of the first layer. The display processor may compose the plurality of layers to generate an image frame for display.
