AMD Touchpad issue

I have Tanshi m15c laptop with amd touchpad. The cursor movements are strange: too smooth and sometimes jumpy. This might be because iichid enables sampling mode. Is there a fix for this?
 
Well the first place I like to start is libinput. You need to identify the touchpad and look at the events.
