Can't shear sheep reliably with touch input

Hi,

 

there is a bug which prevents me to shear sheeps probably, it is the same on android as on windows 10 with a device with touchscreen. The problem is that the "Shear" button only shows up occasionally without hitting the sheep first, hitting it shows the button instantly but the sheep is running away and getting damage ;(

 

ill attach a video where you can see it at about 1 minute

 

cant attach it, to big, here's a link:
