I didn't expect this to hit HN so soon! Feel free to try WebRender 2 out--it should hit nightlies within a day or two--but note that this is still under heavy development, and there are a lot of very important optimizations that have yet to be implemented. The primary focus so far has been correctness and validation of the approach. At some point either gw or I will probably write up an overview of how WebRender 2 works. It's conceptually similar to, and shares most of the code with, the original WebRender. Briefly, the main advantage of WebRender 2 is that it uses an approach loosely akin to tiled deferred rendering to minimize overdraw, whereas the original WebRender more or less performed forward rendering only. We also have a path forward to subpixel AA (though not implemented yet) without requiring readback, expensive framebuffer ping-pong, or GL extensions.
