Strange scroll bug POINTER_SCROLL_WHEEL incorrect events

I've probably not the first with this kind of error, but i really can't figure out what's wrong here. Scroll is sending incorrect events randomly, the libinput debug-events output is the following:

 event30  POINTER_SCROLL_WHEEL    +6.508s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +6.558s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +6.980s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +7.390s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +7.910s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +8.116s	vert -15.00/-120.0* horiz 0.00/0.0 (wheel) <--- this one is wrong
 event30  POINTER_SCROLL_WHEEL    +8.264s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +9.010s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +9.152s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +9.286s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +9.610s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +9.656s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +10.186s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +10.248s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +10.644s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +10.864s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +11.144s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +11.436s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)
 event30  POINTER_SCROLL_WHEEL    +12.080s	vert -15.00/-120.0* horiz 0.00/0.0 (wheel) <--- this one is wrong also
 event30  POINTER_SCROLL_WHEEL    +12.162s	vert 15.00/120.0* horiz 0.00/0.0 (wheel)

So the result of this is when i am scrolling vertically DOWN only, sometimes it flickers up giving wrong results. Libs i have installed

libinput 1.19.2-1
xf86-input-evdev 2.10.6-3
xf86-input-libinput 1.2.0-2
xorg-xinput 1.6.3-2

And of course this affects every application from xfce4-terminal to every browser

UPD: Changing mouse helps, but no problems were found with previous mouse on previous arch installation ;(
