I suffer from the limitations of both X11 and Wayland. Some things work in one and not the other, it's a trade off. In Wayland I can use different scaling for each monitor (in exchange for a LOT of RAM). But in X11 I can use Barrier to share my mouse / keyboard with my other computer. So I use one when I have a second monitor and have to restart my session when I use a second computer :'(
Please fix this!
