Details

With both apz.axis_lock.breakout_angle and apz.axis_lock.lock_angle both set to M_PI / 4, we can get gestures with an exactly 45 degree angle and enter a PANNING state. We should always bind to an axis on mac.

Steps to reproduce:

  • Set both apz.axis_lock.breakout_angle and apz.axis_lock.lock_angle to M_PI / 4
  • Navigate to a a page that can scroll both on the horizontal and vertical axis
  • Input several 45 degree gestures

Expected results:

An axis is chosen and we scroll on only one axis

Actual results:

On occasion the angle is exactly 45 degrees and we scroll on both axes

Severity: -- → S3

Priority: -- → P3

Even for scroll gestures which start axis locked, it's pretty easy to unlock in the middle of the gesture by scrolling diagonally.
