In another case, it's losing track of one of my fingers mid-scroll:

event16 - gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
event16 - gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
 event16  POINTER_AXIS     +10.66s      vert 0.00 horiz -1.11* (finger)
event16 - gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
 event16  POINTER_AXIS     +10.67s      vert -2.27* horiz -2.69* (finger)
event16 - gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
 event16  POINTER_AXIS     +10.68s      vert -1.94* horiz -1.27* (finger)
event16 - gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
 event16  POINTER_AXIS     +10.69s      vert -2.59* horiz -2.69* (finger)
event16 - gesture state: GESTURE_STATE_SCROLL → GESTURE_STATE_SCROLL
event16 - touch-size: end touch
event16 - button state: from BUTTON_STATE_AREA, event BUTTON_EVENT_UP to
BUTTON_STATE_NONE
 event16  POINTER_AXIS     +10.81s      vert 0.00* horiz 0.00* (finger)
 event16  POINTER_MOTION   +10.81s       -0.46/ -1.41
 event16  POINTER_MOTION   +10.82s       -0.85/ -3.20
 event16  POINTER_MOTION   +10.83s       -0.63/ -3.89
 event16  POINTER_MOTION   +10.84s       -0.63/ -3.56
 event16  POINTER_MOTION   +10.85s       -0.32/ -3.56
event16 - touch-size: begin touch
event16 - thumb state: THUMB_STATE_MAYBE → THUMB_STATE_NO
event16 - touch is speed-based thumb
event16 - button state: from BUTTON_STATE_NONE, event BUTTON_EVENT_IN_AREA to
BUTTON_STATE_AREA
 event16  POINTER_MOTION   +10.88s        0.00/ -3.56
 event16  POINTER_MOTION   +10.90s        0.00/ -0.97
 event16  POINTER_MOTION   +10.91s        0.00/ -4.19
 event16  POINTER_MOTION   +10.92s        0.00/ -2.59
 event16  POINTER_MOTION   +10.93s        0.00/ -0.97
 event16  POINTER_MOTION   +10.93s        0.00/ -3.56
 event16  POINTER_MOTION   +10.95s        0.00/ -0.97

But I'm using v1.10.4 with the old 60:40 thresholds. So that one should be
fixed by bug 103572
