Problems with xf86-input-synaptics 1.5.99.901

[Ilya Ilembitov]

Hi, all.

I have HP Envy 13 which uses a single button design of Synaptics Clickpad.

Using Arch Linux I have updated to xf86-input-synaptics 1.5.99.901
which is supposed to bring proper support for my touchpad.

What works:
-drag and drop
-two-finger scrolling
-tap to click, double tap to click for right button

What doesn't work:
-right click
-button areas recognize movements, so the cursor jumps a lot during
drag and drop

What can I do to fix the issues?
