Touch xy seem to be duplicated under heavy load

Hi all, I noticed that under heavy load, the touch event gets fired appropriately, however the xy coordinates are sometimes wrong (to be precise: they are a duplicate of the previous touch event).

Trying out this code

Bangle.on('touch', function(button, xy) {
  console.log("coords are", xy);
});

setInterval(() => {
  g.clear();
  for (let i = 0; i < 40; i ++) {
    g.fillRect(0,0,50,50);
  }
}, 50);

and then quickly touching the screen, alternating between the upper edge and lower edge, does register the correct amount of events, however a quick top, bottom, top tap results in this console log

coords are { "x": 103, "y": 9, "type": 0 }
coords are { "x": 117, "y": 8, "type": 0 }
coords are { "x": 117, "y": 8, "type": 0 }

It doesn't reproduce every single time, however it happens often. Any idea how this could be fixed?

Thank you
