Two questions: a) does using Wayland in Fedora 23 offer the ability to scale the UI across different DPI monitors in a consistent way in Fedora 23? And b) am I going to get significant problems with Wayland on applications such as VirtualBox (running Windows inside it), terminal emulators Tmux, etc, and of course, browsers (Firefox?)? Ie is it usable without too much compromise?
