--- Comment #19 from Zamundaaa <[email protected]> ---
Cursor movements have much lower latency than compositing, and we composite on
every image update. The dropped frame is afaict really just from that change in
latency, and pretty much expected.

Making cursor and overlay image updates async (again) will happen at some
point, but doing them correctly while also avoiding clients going crazy with
cursor surface rendering is not all that trivial.

The software cursor cannot be affected by the commit you linked. Are you sure
you applied it correctly? You can check with drm_info.
