In general, techniques are disclosed for correctly rendering areas on a display in which two or more shadows overlap. More particularly, two or more shadow regions (based on the arrangement of overlapping windows/shadows) are identified and merged in a top-down process so that no region's shadow is painted or rendered more than once. To accomplish this a shadowbuffer (analogous to a system's framebuffer) may be used to retain windows' alpha information separately from the corresponding windows' shadow intensity information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Unitary shadows","description":"Methods, devices, systems, and computer readable media to improve the operation of window-based operating systems is disclosed.
