Many Linux distributions including the official Debian based Rasbian distro for Raspberry Pi makes uses of X11 or XServer windowing software to render the user interface, the problem is X11 is not optimized to use the graphics core of RasPi efficiently resulting in degraded lagged window composition. The Raspberry Pi core team has now decided to bypass X11 completely and move over to the open-source Wayland composition protocol.

The overall results are really exciting, while still in development the team prepared a video demonstration comparing the two and results are really promising. The video comparison and links to details including how to install the technology preview on Raspbian are shared below (click Read more).
