Here’s the sad truth that Wayland haters hate: Wayland is way more performant and streamlined. X11 is an overly patched mess.
Everytime I had to install a distro, EVERYTIME I had to do some textfile hacking to avoid screen tearing with X11. Turns out in Wayland that is a virtually impossible bug.
Forget about making touchscreens work properly in X11, specially with a secondary screen.
I also remember all the weird bugs that appear in X11 when you have 2 screens with different scaling. No issue at all with Wayland.
Pretty basic stuff in any modern setup.
Wayland performs perfectly on platforms like KDE Plasma or Gnome. I miss no feature. It just requires that some propietary apps realise its potential. And that is what is already happening and will happen throughout 2024.
