While it has a bunch of patches that can boost gaming performance and such it’s stability takes a hit in some areas. It’s also not quite as user friendly as other options. It can be better for those looking for a fedora base if that’s what they prefer, tho.
It’s also extremely opinionated & while it’s a great fit for those who have a matching use case, for general uses it’s a bit too opinionated.
It’s neither the worst, nor the best. It just highly depends on use case.
Java aplications and old applications must use a backwards compatibility layer that can cause flicker and bad font rendering.
There have been efforts to provide better support for Java applications on the Wayland. For instance, the OpenJDK project has been making progress on implementing native “pure” Wayland toolkit integration not dependent upon XOrg/X11 or XWayland.
but not all toolkits support it natively and few are easy.
There have been significant developments in providing native support for Wayland in various toolkits. For example : Clutter, GLFW 3, SDL, GTK 3.20+, QT5+, EFL, Slint, Iced & OpenJDK. Just to name a few.
While it is true that not all toolkits have full native support, ongoing work is/has largely shifted towards much better Wayland support.
Wayland is a communication protocol that specifies the communication between a display server and its clients, designed to be a replacement for the X11 window system protocol and architecture.
I might be a little nitpicky here, but I feel it’s an important distinction to make as there is no single common Wayland server like Xorg is for X11.
A display server using the Wayland protocol is called a Wayland compositor, as it additionally performs the task of a compositing window manager.
Xorg on the other hand is basically one fat display server designed like a house of cards that everyone uses.
