However, it seems Apple is ditching Intel processors for future Mac's in flavor of their own ARM-based processors. Virtualization software: Parallels Desktop for Mac version 16.2.4 (49160) Pen display: XP-Pen Artist 12 Pro with driver version 2.18 () on Mac GPU: Iris Graphics 655 (Parallels Intel 14.7.8 driver with OpenGL 3.3) But now we get inverted Y-tilt even on XP-Pen , so we believe Parallels should change its way interpreting the value for Windows Ink. At that time, we thought it could be specific to this sidecar setup so we just reversed it back via Expresii's setting (as shown in the above video) for correct control. She was using iPad + Apple Pencil for stylus input via Sidecar, and she also got that up-side-down tilt. Previously, a user sent us a video of Expresii running on Parallels 15.

Previously, we have the tilt reading correct on Windows 10 (via Windows Ink or vendor's own wintab32.dll) for various tablet vendors including Wacom, Huion, XP Pen & Microsoft Surface Pen, so we believe we're reading the tilt values correctly from the app.

As you can see in the video below, we get tilt reading for both pen hovering and touching the surface. We don't even need to install driver for the pen display before we can the correct tile values via Windows Ink. The tilt reading is also correct out of the box on native Windows 10.
