I suppose it really depends on when you tried it. Ubuntu 23.10 has been working quite well on Wayland. I haven’t once failed down to X, and the only papercut I run into now is with differently scaled displays (100% and 150%) where OBS will crash the session when moving back and forth.
Everything else seems good as I haven’t really seen anything else break at all and I use Firefox, Kdenlive, Audacity, lots of chat apps, and played some games. Specifically, playing Vivaldia 2 while I was remotely compiling Gentoo using OBS to livestream.
