I tried switching to Wayland on Mint, it did not go well. Unfortunately I do not care to follow an hour long guide to figure out how to get it to run games properly.
A dedicated Github repository was created for issues related to Wayland, whether they need fixing in Cinnamon, in an XApp project, a Mint tool or anything software project we maintain: https://github.com/linuxmint/wayland.
In terms of timing Wayland support doesn't need to be fully ready (i.e. to be a better Cinnamon option for most people) before 2026 (Mint 23.x). That leaves us 2 years to identify and to fix all the issues. It’s something we’ll continue to work on and improve release after release.
