Bug#951532: libinput: Touchpad behavour changed

[Lukas Straub <lukasstraub2@web.de>]

Source: libinput
Version: 1.15.1-1
Severity: normal

Dear Maintainer,
Since Version 1.15.1-1 the behavour of the Touchpad changed. I have a "unified" Touchpad i.e. no physical seperate buttons, the whole touchpad is pressed down.
-It's now impossible to do a middle or right-click and drag (It will always send left-click)
-If I have my finger on the touch area first, I can do left-click and drag. If the mouse button is pressed first, it's impossible to drag (the pointer stays where it is). 

These problems go away if I downgrade to libinput-bin 1.14.3-1.

Regards,
Lukas Straub
