A graphics pipeline may be partially or completely shut down based, at least in part, on the presence of non-transparent objects in a graphics layer. Any regions of the graphics layer that include one or more non-transparent objects (e.g., semi-transparent, opaque, etc.) may be determined. A video layer and the determined regions of the graphics layer may be sampled. The sampled video layer and the sampled determined regions of the graphics layer may be composited for display. In some instances, it may be determined that the graphics layer includes no non-transparent objects. Upon that determination, the graphics pipeline may be fully shut down and the video layer may be sampled and composited, without sampling and/or compositing the graphics layer. |
