Hi, I'm glad for you to interest this project.

Currently, coordinated graphics has two kind of GraphicsLayer tree: CoordinatedGraphicsLayer tree on the main thread in Web Process, GraphicsLayerTextureMapper tree on the rendering thread in UI Process.
After this meta bug completes, we can get GraphicsLayerTextureMapper tree on the rendering thread in WK1 also. It means Texture Mapper runs off the main thread.

You can get more information from our design document. https://docs.google.com/document/pub?id=1UoI1zk-6nTUFtz8i4evURM8aQIjkDRC8boO1zPdMMBg
