            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.
