> Can the compositor replicate the input-to-pixel latency of uncomposited x11 on low-end devices or is that a class of performance we just have to sacrifice for the frame-perfect rendering of wayland?
well, the answer is just no, wayland has been consistently slower than X11 and nothing running on top can't really go around that
Can you cite any sources for that claim? I found this blog post that says wayland is pretty much on par with X11 except for XWayland, which should be considered a band-aid only anyways: https://davidjusto.com/articles/m2p-latency/
Here's one article: https://mort.coffee/home/wayland-input-latency/
It's specifically about cursor lag, but I think that's because it's more difficult to experimentally measure app rendering latency.
> wayland has been consistently slower than X11
Wayland is a specification, it has an inability to be "faster" than other options. That's like saying JSON is 5% slower than Word.
And as for the implementations being slower than X, that also doesn't reflect reality.

There is no Wayland to run on top of as its a standard to implement rather than a server to talk to.
