Correct Tilt reading on Native Windows 10
Previously, a user sent us a video of Expresii running on Parallels 15. She was using iPad + Apple Pencil for stylus input via Sidecar , and she also got that up-side-down tilt. 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. 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.
