Windows can't set a Icon on Wayland. The set the Name of the Desktop
file and the Windows will have the Icon of the Desktop file. On Qt you
can use the setDesktopFileName() function of QApplication for that.
Windows also can't move themself under Wayland. There' a protocol in the
making to allow this
(https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests=
/264),
but it's not there yet. Wayland is in general way more restricted than
X11 and Windows. You should also keep in mind that the behaviour may
differ from Desktop to Desktop.
