Abstract: Techniques are provided for optimizing display processing of layers below a dim layer by a display system. Because the dim layer may partially obstruct, conceal, or otherwise impact a user view of layers below the dim layer, resource-saving techniques may be used in the processing the layers below the dim layer. While these techniques may impact visual quality, a user is unlikely to notice visual artifacts or other reductions in quality in the modified layers below the dim layer. For example, when a dim layer is to be displayed, a GPU can render layers below the dim layer at a lower resolution. Furthermore, the GPU can increase a compression ratio for layers below the dim layer. The low-resolution layers can be scaled-up to an original resolution and the compressed layers can be uncompressed in the display pipeline for display underneath the dim layer.
