I guess it depends on the application.

I have some that just open a GUI and they are fine.

But the list of problems in my programs with wayland is huge.

Most of my applications are desktop background programs that wish to open a
window in a particular place on the desktop screen.
See the attached image of my desktop.
My Desktop-ish launcher (bottom left) . not possible with wayland unless i
add a border and move it ea\ch time it loads.
my GLaunch gambas project manager (bottom right) opens it's window by the
tray icon.  not on wayland though
My Temp, temp monitor, (top right) nope.

It's like with wayland there is no way to bake a decent background desktop
GUI, just ones that open, get used then get closed.
only windows with border/titlebar can be moved.  any kind of code to move a
form seems not possible.

My Gmag app, a simple magnifier using Desktop.Screenshot()  , but not with
wayland as Desktop.Screenshot() using Desktop.Portal would now be more
appropriately named Desktop.OpenScreenshotDialog()

I just had to track down a bug in my Blockski+ game that was due to
something like this...
Public Sub Form_Show()

  Me.Activate() ' ensure form is the active one

End

That worked okay on x11 but now I found with wayland that caused an
infinite loop as the Me.Activate() called Form_Show again.
(it's possibly useless code anyway)

Sigh ,new system, new problems

But I guess it's as Ben says, all we can do is pray that wayland team sorts
these incompatibilities out!
