Do anyone have Lenovo X220 with Sierra? Do you have trackpad issues?

I successfully installed a Sierra to a X220. I works really well, but I have problems with the trackpad.

Double finger scroll and gestures are working, but when I enabled the secondary click to the two fingers tap, it made lot of false positives during scrolling. I had to disable it because it was pretty annoying.

As I disabled it now it highlights texts/images randomly on webpages during scrolling.

Also the drag&drop is pain in the back when I make the click on the trackpad (with my thumb), and try to navigate the grabbed item with my other finger. Any time I lift my finger the item jumps to a totally random place on the screen. It may not recognise well the two fingers on the trackpad.

The last one is my least concern because I can use the buttons for the trackpoint for drag and drop. But the random highlights and secondary clicks are annoying.

Did you have this issues as well, and found some solution, or that is normal.Or there is something physically wrong with my trackpad, and I should replace it?

Thanks!
