Verified fixed in chromium 84 (beta). Although that means it's now as good as Xorg sessions, which isn't really good enough IMHO.

I guess it's probably Xwayland failing to support the more advanced XInput stuff? Note: This bug report is about high precision (and thus low latency) touchpad scrolling. It is not about "Smooth Scrolling" simply because "Smooth Scrolling" actually means something quite different in Chromium. :P Test case: 1. In chrome://flags, set Smooth Scrolling to Disabled and restart the browser. 2. Use your touchpad (usually two fingers) to scroll a web page. Observed: In an Ubuntu session (pure Xorg), the scrolling is noticeably high precision like a Macbook or Chromebook. In a Wayland session however, the scrolling stutters badly like it's still using old-style mouse wheel emulation. Note also: If you have "Smooth Scrolling" enabled then Chromium replaces the stutter with smoother scrolling but you can still tell it's broken in Wayland sessions because the latency is much higher.

Surprisingly, it's Chromium that's broken.
