Could you please let us know which operating system are you using?
Also, please let us know have you tried rolling back the drivers for wacom?
I am on iMac late 2012 on OS X high Sierra.
I have had to go back to a Wacom driver 2 years old for zoom to work with my finger gestures.
I always thought you should always have the latest drivers.
I was wondering if there are any experts on here To answer my questions.
