Every Wayland compositor I could find is a tiling one: sway, river, Hyprland, dwl, niri. If you want windows that float and overlap with titlebars and a taskbar, the way IceWM does it, there's almost nothing. That is Steppewm
I tried it but it was really a struggle to get like OSD or an actual good non-janky taskbar; all implementations are either buggy or cannot be as useful as i was hoping
(I really only use IceWM on systems that would struggle with XFCE.)
