Bug ID: 149347
Summary: [Win] Use tiled drawing for main background layer
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
Assignee: webkit-unassigned at lists.webkit.org
Reporter: bfulgham at webkit.org
When compositing layers are used on Windows, a single large layer is created for the root of the rendering tree. If the markup involves creating large offscreen areas, WebKit can end up allocating a lot of memory.
Instead, we should use the tiled drawing logic for the background layer so that we can limit the amount of memory used.
