Composited desktops have their drawbacks. With a display system like X11 or old-school GDI-based Windows, draws to the display are next to immediate, whereas with composited desktops, everybody has to draw to a back buffer, then the back buffers have to be composited together on the final display, adding at least one frame of latency. Mouse cursors have been a hardware sprite since the 90s, but Wayland compositors may favor using the GPU to draw a soft cursor. It'd be interesting to see a compositor that can speak Wayland, yet performs immediate, region-clipped draws of all windows like X11 conventionally does.
