Pen randomly stops working properly while writing

[Demisu]

Hello,

Recently my HP Pen (included with my laptop) started doing weird things. When I'm writing on, for example, OneNote, after a random period the screen goes black for a short while and then comes back. After this, the screen will turn black again everytime I touch the screen with my pen and this happens untill I restart the laptop. On some apps like OneNote, if I change the pen color from black to a special one (like rainbow), everything works fine, but as soon I select again black or any "normal" color everything starts again. Any ideas how to fix this?

Also sometimes (but this is pretty rare) the pen stops writing for no reason and there can be 2 scenarios following:

1) it starts to write again, but everything is written at "max pressure" even when I only gently touch the screen

2) it will never start to write again, the only way to fix this (and the n.1) is to remove the battery

Are those problem related in any way?

I have already tried to reinstall Windows and update drivers but nothing changed
