> kept scrolling too long after releasing
this is probably another thing
in gtk, kinetic scrolling stops after you put a finger on the touchpad
(zwp_pointer_gesture_hold_v1 event), but in firefox it doesn't, you have to wait

Bug description:
This is an issue which has troubled me for a while. Anecdotally,
scrolling feels way too fast in GNOME on Wayland compared to on X11. I
finally tested it semi-scientifically, and it seems like GNOME on
Wayland scrolls almost exactly 1.5x faster than GNOME on X11.
I tested this by testing how many lines are scrolled from a full two-
finger touchpad swipe from the bottom of my touchpad to the top of my
touchpad, and logged a few attempts in both X and Wayland. I kept
track of the results in this spreadsheet:
https://docs.google.com/spreadsheets/d/17EaBM5Pgt7GdnnzcN2Vchk4kfT7IZ6i4qZ0zpVRGLhc/edit?usp=sharing
I scrolled in one of my own GTK applications
(https://github.com/mortie/lograt) because it lets me easily see how
many lines I scrolled. Attach is a video of one full scroll on X11 and
one full scroll on Wayland.
This testing was performed on a Dell XPS 13 9343, but I've also used
Ubuntu on a Dell XPS 9575 where GNOME Wayland scrolling also feels way
too fast. I don't have other hardware to test on.
This has been an issue on both Ubuntu 20.10 and Ubuntu 21.04.
