Krita erratic stylus behavior

Summary

When using a stylus, Krita incorrectly and unpredictably switches between pen and eraser modes. Sometimes when I put the stylus pen tip down, it will switch to the eraser. Other times Krita is stuck in pen mode even when I use the eraser tip.

I've done some work to debug this problem and determined that Krita tablet tester log is inconsistent with xinput events.

I'm using a Wacom AES stylus called the Dell Active Pen (PN557W), which has a single tip and a button that switches the tip between PEN and RUBBER modes.

Steps to reproduce

  1. Do a stroke with the stylus pen tip
  2. Do a stroke with the stylus eraser tip (with the stylus switched to eraser mode if your stylus only has one tip like mine)

8-dimensional planar rotations with Clifford Algebra and GLSL
// This function rotates the 8-dimensional vector v[8] by angle a in the plane swept through vectors fr[8] and to[8].
// It was generated using Sage's CliffordAlgebra module and Sympy's code printing tools.
// Mathematically, the function makes a rotor from the outer product of normalized 1-vectors fr ^ to, then uses that to do a
// sandwich product with v. You can read about this here: https://en.wikipedia.org/wiki/Rotor_(mathematics)
float[8] rotate(float v[8], float fr[8], float to[8], float angle) {
float sin_th = sin(angle*2*PI);
float cos_th = cos(angle*2*PI);
