Please ask on specific bugs if you want to start working on it and needs more guidance. **Technical Info** Start with this overview of [GPU accelerated compositing in Chrome](/developers/design-documents/gpu-accelerated-compositing-in-chrome), which includes an overview of the original non-accelerated path. For current status of feature development, see the [GPU architecture roadmap](/developers/design-documents/gpu-accelerated-compositing-in-chrome/gpu-architecture-roadmap). To suggest and vote on presentation topics, see [Compositor/GPU/Graphics talks you want to see](https://docs.google.com/spreadsheets/d/1IUl8IumXjBvxZVcd-K84uEvMcE71hJSWkHhMn0Lshr4/edit?usp=sharing).
