Summary [CSS Regions] Elements with 3D transforms do not create composited layers
Mihai Balan
Reported 2013-05-27 07:47:22 PDT
Elements in the document flow (flow-into: none) create a composited layer when they have a 3D transform applied to them. When flowing such an element inside a named flow the composited layer isn't preserved/created anymore. In the attached file, toggle between `flow-into: flow` and `flow-into: none` for the gray div with text - when flow-into is specified, a composited layer is no longer created (this can be inspected via the Debug > Drawing/Compositing flags > Show compositing borders or Debug > Show RenderLayer tree menu entries in Safari/WK nightly)

Fixed in WebKit nighly which was expected after we enabled ACC for elements displayed in regions.
