i am using wayland on fedora 42 + kde, it's fine what are you talking about? if you stop running sway/hyrpland rices you'll be fine.
What if we want some of the other desktops out there?
Examples:
I like Macs and macOS, with a global menu bar. I like Ubuntu's Unity desktop. It doesn't work on Wayland and won't. Unity8, AKA Lomiri, does but it is intended for handhelds with touch and is badly compromised. No global menu bar, for instance.
What if we want something NeXT-like? I like GNUstep. Neither GSDE nor NEXTSPACE supports Wayland.
I like Xfce. It has an experimental version but keyboard window management is broken. Xfce's compatibility with standard Windows keystrokes is one of the reasons I like it. It seems to me Wayland folks don't know these and I've yet to see a Wayland environment that supports them. E.g. Alt+Space, X to maximise. Alt+Space, N to minimise.
I want full title bars, so I can use the scroll wheel on them to roll them up, as in Windowshade.
E.g. https://www.windowmizer.com/
I also want to be able to middle-click the title bar to send that window to the back of the stack. Once _every_ Linux desktop did this, but GNOME started software rot by getting rid of title bars in favour of "client side decorations" and the feature started to disappear.
What if I want one of the lightweight Windows-alike desktops? MATE, Trinity, EDE, XPde? No Wayland support.
What if I want a Chinese desktop with a bit of Win7 bling? DDE and UKUI both don't support Wayland.
What if I want a different trad Unix environment?
CDE, nsCDE, Maxx Interative, OLWM... none work on Wayland.
Amiga style: amiwm doesn't work.
Classic Mac style: mlvwm doesn't work.
