Summary: [Texmap] TextureMapper creates two many big
intermediate surfaces
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Keywords: Qt
Severity: Normal
Priority: P2
Component: Layout and Rendering
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: noam.rosenthal at nokia.com
Currently TextureMapper is very generous in creating intermediate sufraces. The current algorithm always uses the viewport size for an intermediate surface, and it chooses to create a surface for unnecessary layers, such as ones with reflection and no opacity.
Since intermediate surfaces are a performance and memory hog, optimizing this is of high value.
