FRAME INVALIDATION CONTROL WITH CAUSALITY ATTRIBUTION

摘要

Developers receive automatically designated property change events which caused invalidation of a rendered frame. Some embodiments control display invalidation in part by identifying higher-level frame bounding events in an execution trace, and applying at least one display invalidation constituency filter to lower-level thread events within a frame creation period, thereby obtaining a display invalidation constituency sequence of one or more display invalidation events. The sequence may include a layout property change event and/or a render property change event which invalidated the frame. An initial part of the sequence is designated as a display frame creation cause. Displayed frame invalidation is controlled by altering the display invalidation constituency, e.g., by manual or automated layout/render property change event elimination or event sequence location change, by a reduction in computational resource usage (e.g., memory usage, graphics processor chip usage), and/or by a reduction in thread execution time which provides a faster frame rate.
