i agree with a lot of this; > I was not happy so see that my mouse felt laggy i also noticed this immediately and it was infuriating. my display runs at 240hz, so there must be at least 2, maybe even 3 frames of latency for it to be noticeable. it's made more perplexing that wayland was supposed to represent a reduction in latency. > Out of the box, there’s a bit of that in wayland too, but sway has a way out: max_render_time. this is possibly the worst way you could reduce input latency - mostly because of the tail-end of render times will be the most noticeable and the worst performing - please never do this unless you're trying to make your users inexplicably angry :) > when really, other X servers exist, and have varying degrees of support for the extensions Xorg supports a non-point here from me but i only know of XOrg and Xfree86, and i think the last time i tried that, linux kernels started with a two.. :)
