Intuos Pro M jumping cursor

Hi!

I recently noticed an issue with small movements on my Intuos Pro M gen 2.

When i draw short lines (really short, around 1 mm movement on the tablet) the cursor jumps to the beginning point of the previously drawn line and starts the new line from there. Here's a full screen screenshot, for scale. The middle part is drawn, the bottom is enlarged.

I'm using a 2020 Intel iMac 5K, with up to date OS.

I've tried the oldest possible Wacom driver and the newest, both produces this behaviour.

Tried different drawing apps (CSP, Krita, Affinity Photo), cursor does it everywhere.

Also tried it on an old Thinkpad, with Windows 10 and newest Wacom driver, which still produced the same issue, although less frequently.

Tried different settings as well, like softer-firmer nib feel, tip-up assist on-off, but nothing helps.

Is this a driver issue?

Or a faulty hardware? If it is, is it the pen or the tablet thats faulty?
