Description Alvin Wong 2021-05-05 09:53:35 UTC

SUMMARY

When the canvas is rotated, with the brush smoothing st to "stabilizer" and "stabilize sensors" set to off, the stylus tilt direction is rotated incorrectly.

STEPS TO REPRODUCE
1. Set cursor outline shape to "tilt outline" or choose a brush preset that uses tilt angle and direction
2. Set brush smoothing to "stabilizer" and disable "stabilize sensors"
3. Rotate canvas
4. Draw on the canvas

OBSERVED RESULT

Tilt direction is wrong.

EXPECTED RESULT

Tilt direction should not be wrong.
