<pre>Okay, I caught the flow when 3-fingers touch is not detected, and nothing
happens. It looks like 2-finger touch and 1-finger touches at close time, e.g.:
Sample 1:
E: 34.311155 0001 0145 0001 # EV_KEY / BTN_TOOL_FINGER 1
E: 34.334286 0001 0145 0000 # EV_KEY / BTN_TOOL_FINGER 0
E: 34.334286 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1
E: 34.457612 0001 014d 0000 # EV_KEY / BTN_TOOL_DOUBLETAP 0
Sample 2:
E: 47.998600 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1
E: 48.072614 0001 0145 0001 # EV_KEY / BTN_TOOL_FINGER 1
E: 48.072614 0001 014d 0000 # EV_KEY / BTN_TOOL_DOUBLETAP 0
E: 48.116407 0001 0145 0000 # EV_KEY / BTN_TOOL_FINGER 0
Sample 3:
E: 73.864204 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1
E: 73.968262 0001 0145 0001 # EV_KEY / BTN_TOOL_FINGER 1
E: 73.968262 0001 014d 0000 # EV_KEY / BTN_TOOL_DOUBLETAP 0
E: 73.995397 0001 0145 0000 # EV_KEY / BTN_TOOL_FINGER 0
Sample 4:
E: 82.847529 0001 0145 0001 # EV_KEY / BTN_TOOL_FINGER 1
E: 82.881636 0001 0145 0000 # EV_KEY / BTN_TOOL_FINGER 0
E: 82.881636 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1
E: 82.983867 0001 014d 0000 # EV_KEY / BTN_TOOL_DOUBLETAP 0
Worth emphasizing that for some reason these does not cause any action at all.
E.g. I have selected a text, and rationally after such a misdetected touch
shall happen either α) a menu pops up, or β) the selected text gets unselected.
The samples I shown above cause neither α nor β, like if they get completely
ignored by libinput.</pre>
