alt Hacker NewsWasn't one of Wayland's key design features combining the window manager and compositor? I am not too familiar with its history but surely there have been presentations or papers about the Wayland designers' reasoning for doing so.

When the window manager is a separate process with async communication between the WM and display server things can get out of sync for a frame or two which leads to visual artifacts. In Wayland the window manager works synchronously with the compositor so that it's never out of sync.

Well, that's exactly what the article is about. Wayland put all together into one process I order to avoid unnecessary context switch. This protocol aims to keep the performance advantages of Wayland without giving up on separation of graphics c server and window manager.
