Recently I installed Linux Mint 20.2 Cinnamon.
Touchpad multi finger behavior is strange and annoying. When I tap with two fingers exactly at the same time, it performs right click and if one of my fingers touch a little later than the other one, it performs middle click. Three finger tap doesn't work. Changing Click Actions in Mouse and Touchpad seems to have no effect. Currently I disabled Tap to click to prevent accidentally paste, closing tabs, opening links, etc. while performing Two-finger scrolling or tapping.
Here is output for $ xinput --list-props X command:

In Windows touchpad behaves OK for two and three finger actions. I think Ubuntu and previous versions of Linux Mint were OK too. External mouse works well.
How should I set three fingers for middle click and two fingers just for right click? (or at least disable middle click for two fingers)
