830218 - Progressive Draw causes recomposites when updating displayport outside the screen

Status: NEW

(Core :: Graphics: Layers, defect)

Description

[Benoit Girard (:BenWa)]

STR:
1) Turn on the new cleopatra feature 'Show Frames Boundary'.
2) Looking at a task.js profile the last few frames where progressive draw transaction come in we composite new frames even if we're updating outside the screen.

This is mostly a battery usage issue.

Interesting - pretty minor though. I wonder how the hit of checking whether contents is on the screen or not compares to just doing the composite...
