Ever since libinput.
- Moving the mouse into a new window and scrolling, the first scroll event seems discarded in GTK applications (like Chrome..), causing frustration..
A quick workaround for some GTK apps (Chrome esp.) is to remove libinput and replace it with evdev.
- May not be recommended for touch interface users:
apt install xserver-xorg-input-evdev
apt purge xserver-xorg-input-libinput
(Tested on Kubuntu 20.04.)
Dependencies being removed..
- On my system that was limited to one: "xserver-xorg-input-all"
Mouse acceleration settings in the desktop environment needing to be re-adjusted.
