1. A method of display processing, comprising:
identifying a subsection of a set of frame layers, the identified subsection corresponding to a lower pixel density region, relative to at least one other region, of a display, wherein the lower pixel density region of the display comprises a lower quantity of pixels capable of presenting pixel data on the display relative to the at least one other region;
blending first pixel data for each frame layer corresponding to the identified subsection to generate second pixel data;
populating a buffer layer based on the second pixel data;
blending pixel data from the set of frame layers and the buffer layer to generate a blended image; and
transmitting the blended image for presentment via the display.
