Implementing Threaded Accelerated Compositing in WebKit GTK+ Gwang Yoon Hwang 揃 際際滷s The main thread is where everything gets executed including layout and scripting. Thus, running compositing in the main thread severely limits responsiveness and rendering speed. By having a separate thread for compositing, we can bring a significant performance improvement in scrolling, zooming, and rendering, especially CSS3 animations. Currently, several ports have already implemented off足the足main thread compositing. Coordinated Graphics System, which is used by Qt and EFL, runs accelerated compositing in the UI Process. Compositor Thread used by Google Chrome runs the compositing thread off the main render thread in the Renderer Process. Our Threaded Compositor is another accelerated compositing implementation, which is a threaded variant of Coordinated Graphics System. We are currently contributing Threaded Compositor to WebKit GTK+. Threaded Compositor makes WebKit GTK+ render CSS3 animations faster. Threaded Compositor brings a few benefits compared to the current Coordinated Graphics System. Firstly, by performing accelerated compositing in the Web Process, the UI process is isolated from the crashes caused by GPU driver bugs. Secondly, by not performing accelerated compositing in the main thread of the UI process, the UI process becomes more responsive to UI events. In this talk, we will cover how we brought this feature to WebKit GTK+, and its current status. Additionally, optimized features for embedded systems such as memory management will be discussed. Gwang Yoon is a software engineer at Company 100, working on GPU acceleration for WebKit in embedded systems. He is interested in the WebKit rendering system, especially accelerated compositing and accelerated 2D vector graphics on embedded GPUs.]]>
