I'm not switching on my main laptop until xwayland app scaling is figured out. Either figure out how to make the apps scale properly or just leave them tiny on my screen. None of this stretching them to fit and making them blurry bullshit.

I use it on everything else because all my other computers don't have high dpi screens.

i switched my desktop to wayland a few months ago due to weird performance issues in some 3D applications

it went mostly flawlessly, i haven't had much if any issues in terms of app support, as long as your wayland compositor supports xwayland, everything should work pretty great!
the application ecosystem isn't as widely developped though, so you may run into issues if you try to use standalone window managers/compositors like sway, hyperland, etc… but besides that, everything's been great for me!

I can`t give you any technical details, but real-world ones -- it (drastically) decreased my cpu temps and cpu usage, while providing a slightly better performance overall.

t. Tested this on a rpi 4 while running Doom 3 (the closest of a "Crysis for rpi 4") a couple years ago. Pretty sure its even better right now.

I could not turn off mouse acceleration, which was a deal-breaker for me.

Actually not Wayland's fault if I remember correctly, something about libinput changing it's format, and my window manager wasn't compatible with it yet. After trying for several hours I found a bug report (can't find it right now). The Devs thought it was a minor issue, but for me it was huge so I decided I'll wait another year.

I must say, Wayland was smoooooth, didn't even experience X as slow until I tried Wayland.

I just distro hopped to a distro that ships wayland by default and I've got from a near flawless linux experience to an awful experience. I am gonna have to be careful what distro I recommend to people because I dont want anyone's first linux experience to be with wayland. So many issues and every single time its wayland related with no fix. I ended up going back to x11. -NVIDIA graphics card user with KDE plasma.

On my surface go 3, I used pop os at first and the screen tearing was so bad that I stopped using it. I then changed for arch with gnome on wayland and everything works much better.

Though, for my main computer, I recently switched my main OS from Windows and went for Hyprland on Arch. I love it. Most applications run fine. Though I have a 3080. This means that most electron apps are very slow, almost unusable. Also, some applications just refuse to open, notably Plex. For jellyfin, half the time the screen is black and I need to restart the app. I also have a KVM switch that I use for my work computer. When I switched to it and came back, I got a red screen of death for which I had to exit Hyprland and get back to SDDM to log back in. I was able to start and play games though. Global shortcuts didn't work easily (feature, not a bug), so I want to use a support app for Path of Exile. Impossible on Wayland. And finally, I tend to use a screenshoting tool. Flameshot isn't available on wayland so I used snappy, but it doesn't freeze the frame, rendering it useless.

Now I switched over qtile in X11. Everything works fine, electron apps are much more snappy. Most importantly, the WM doesn't crash when I use my KVM, so my sound device works perfectly. The only issue I'm facing is the audio, there seem to have a very small delay (I'm using pipewire).

The only thing that I miss now is a way for me to assign an audio output to an application so that if I close the application it even restart my computer, that assignment is still remembered. Currently I have a tool that does that that I autostart with my WM, but it doesn't redirect the audio, it just adds the other assignment without removing the default audio output.

There you go, wayland is not recommended if you have a nvidia GPU, even though it still works.

I use xmonad and won't switch until there's a viable alternative (probably never).
