Description Brien Dieterle 2017-08-30 05:29:54 UTC
This is only a problem in Mac OS.  Tested Linux with same hardware.

Tried 2.7.11 from website, as well as latest dev build in MacPorts

MacOS 10.11.6
Install wacom drivers from wacom
attach wacom tablet and stylus with tilt support
xinput test <dev id of pen>
observer x and y tilt values.

Expected:  X-Tilt should have negative values tilted left,and positive values tilted right.  Y-Tilt should have negative values tilted forward, and positive values tilted back (towards the user).
Actual:  The Y values are inverted.

Windows and Linux conform to the document from Wacom.
