libinput-debug-events --enable-tap with semi_mt=true and patch applied
With your patch, I successfully get the expected triple tap behaviour. Extract
from the logs:
tap state: TAP_STATE_IDLE → TAP_EVENT_TOUCH → TAP_STATE_TOUCH
tap state: TAP_STATE_TOUCH → TAP_EVENT_TOUCH → TAP_STATE_TOUCH_2
tap state: TAP_STATE_TOUCH_2 → TAP_EVENT_TOUCH → TAP_STATE_TOUCH_3
touch x/y: 959/1062
touch x/y: 959/1062
touch x/y: 959/1062
Is this patch ready to be pushed to libinput or would it break other touchpads?
