Hi Han, Allowing yourselves to place multiple windows where you want it then isn't going to solve that problem, since users can still drag them around, minimize them, etc. Multiprocess rendering is a bit tricksy, and there's no standardized way to do it right now. The traditional technique is to build your own Wayland compositor inside your application, which is a bit heavyweight, and then use wl_subsurface to composite the results. This is what e.g. WebKit2's architecture does, and it's something I've tried to implement in the past [0]. As the scope of a Wayland compositor becomes larger and larger over time, I think this is starting to become a bit impractical. It might be worth looking into a multi-process buffer-sharing protocol as a Wayland extension, since it's a use case that keeps coming up.
