two-finger scrolling is far too fast
Steps to reproduce
- get a laptop with a touchpad
- Open gnome-control-center
- select Devices, then "Mouse & Touchpad"
- click the "Test Your Settings" button on top
- scroll up
Current behavior
Scrolling is extremely sensitive - on my touchpad it takes about 2cm of dragging to get from bottom to top of the scroll area (maybe 20cm on-screen of travel).
Expected outcome
I would expect the on-screen distance scrolled to be relatively in-line with the physical distance scrolled with the touchpad
Version information
- Gnome 3.28.2
- GTK3 3.22.30-1
- clutter-gtk 1.8.4-1
- clutter 1.26.2-1
- libinput 1.11.3-1
- Arch Linux
Additional information
I tried testing with libinput debug-gui and the scrolling response seems good there, so it seems like the issue is somewhere between clutter and the gnome-control-center mouse test UI.
This is on an HP Spectre x360 laptop, though I don't think it's a hardware-specific issue because libinput seems to be reporting good values.
Let me know if there's any other useful information I can provide.
