No multi-touch with Kivy

Hi everyone I have a Raspberry Pi 3 running Raspbian Desktop Strech, the board is mounting this Waveshare 4" touchscreen with its official drivers and the touch already calibrated.



Installed Kivy and I first tried to run an example written in examples/demo/pictures/main.py to test multi-touch, it runs gracefully but just with single touch functionalities since I cannot zoom pinching or rotating images, I only can move them.



I already checked the config.ini inside the Kivy folder writing these lines because I want multi-touch to be enabled:



[input]
mouse = mouse
mtdev_%(name)s = probesysfs,provider=mtdev
hid_%(name)s = probesysfs,provider=hidinput


The result is that I still have single touch.



I noticed that when I tap with a second finger the mouse coordinates change to the vectorial sum of my two taps, so I guess the multiple touch is recognized by the the touch and misintepreted by Kivy itself



What am I doing wrong? Thanks for the attention
