Since framebuffers are generally advised to handle added than one resolution, they generally accommodate added anamnesis than is all-important to affectation a distinct anatomy at lower resolutions. Since this anamnesis can be ample in size, a ambush was developed to acquiesce for fresh frames to be accounting to video anamnesis after advancing the anatomy that is currently actuality displayed.
The abstraction works by cogent the framebuffer to use a specific block of its anamnesis to affectation the accepted frame. While that anamnesis is actuality displayed, a absolutely abstracted allotment of anamnesis is abounding with abstracts for the abutting frame. Once the accessory absorber is abounding (often referred to as the "back buffer"), the framebuffer is instructed to attending at the accessory absorber instead. The primary absorber (often referred to as the "front buffer") becomes the accessory buffer, and the accessory absorber becomes the primary. This about-face is usually done during the vertical blanking breach to anticipate the awning from "tearing" (i.e., bisected the old anatomy is shown, and bisected the fresh anatomy is shown).
Most avant-garde framebuffers are bogus with abundant anamnesis to accomplish this ambush alike at aerial resolutions. As a result, it has become a accepted address acclimated by PC bold programmers.
