Don't CSS shaders end up exposing the same timing attacks for reading images that WebGL used to before CORS support was added? Basically, build a shader that takes more time depending on the pixels. Use requestAnimationFrame to time how long compositing took, adjust until you overflow a frame. You can now read pixels.
