Running Wayland: It Works, But A Lot Of Work Remains
When loading RebeccaBlack OS, the default user is called "beccaholic" and loads Weston along with a Weston Terminal. This distribution isn't exactly meant for production purposes but as an easy way of experimenting with the latest Wayland components.
The Qt tool-kit is available natively for Wayland with good support under Qt 5.0. With the KDE support found currently in RebeccaBlack OS, this is occurring instead through XWayland.
As one can see, XWayland is still not bug-free with misplaced menus, rendering problems, etc.
