Blink's Layer Tree: Architecture, Rendering, and Performance

The provided text offers an in-depth look into Blink's layer tree, a crucial component in Chromium's rendering engine responsible for transforming web pages into pixels. It explains the architecture of layers, detailing how the Document Object Model (DOM) is processed through various stages like style, layout, and paint, ultimately leading to the creation of layers that are then composited. The article also describes the rendering lifecycle, outlining the steps involved in updating and displaying frames, from initial layout to final GPU composition. Finally, it highlights performance considerations related to layer usage, emphasizing how layers enable hardware acceleration for smooth animations and scrolling, while also cautioning against their overuse and offering debugging tools for optimization.
