0013.222784: /dev/input/event2: EV_ABS ABS_MT_POSITION_X 10880
0013.222788: /dev/input/event2: EV_ABS ABS_MT_POSITION_Y 16640

0013.222811: /dev/input/event2: EV_SYN SYN_MT_REPORT 0
0013.222817: /dev/input/event2: EV_SYN SYN_REPORT 0

if you try to release ONLY one finger it sends:

0013.224284: /dev/input/event2: EV_ABS ABS_MT_TRACKING_ID 0
0013.224290: /dev/input/event2: EV_ABS ABS_MT_TOUCH_MAJOR 0
0013.224293: /dev/input/event2: EV_SYN SYN_MT_REPORT 0
0013.224299: /dev/input/event2: EV_SYN SYN_REPORT 0

In this stage, release for both touch points has been sent.

Expected result:
Release event should be sent only for released touch point,
regarding the second one - should be sent "stationary" event
