Machine information: OS: Manjaro Linux x86_64 Host: 80TG Lenovo V110-15IAP Kernel: 5.19.1-3-MANJARO DE: Plasma 5.24.6 Xorg WM: KWin CPU: Intel Celeron N3350 (2) @ 2.400GHz GPU: Intel HD Graphics 500 Firefox: 103.0.2 (x64)

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

  1. Download Firefox and another application with direct input (Opera or Telegram for example)
  2. Scroll Firefox
  3. Scroll another application

Ok I solved that in 1m of google-searching: set environment variable MOZ_USE_XINPUT2=1 I'm still feeling weird scrolling but now I can scroll smoothly with touch pad. I don't think "weird scrolling" is a bug.
