> There's none that I can notice. Mice cursor are rendered with hardware support when available. Not sure what you reference is here.
Some compositors don't use the hw cursor plane. All others that do don't update the cursor position asynchronously on mouse events, just once on the next swap. Those cases add an extra half-frame latency on average. It's worse at lower refresh rates.
