Cintiq Pro 24 Pen Pressure issue

[PatrickvanR]

Having some issues with pen pressure on my Cintiq Pro.

In Photoshop, sometimes the pen pressure bugs out and doesn't do anything (very randomly)

In Zbrush, sometimes there is barely any pen pressure unless I hit the hotkey for repeating the stroke, then it goes full pen pressure, has anyone seen this before?

Running Windows 10 with the latest Cintiq driver, already tried uninstalling and reinstalling the drivers to no effect.

I'm not 100% sure, since it's been happening for a while, but could this be because of the latest version of Windows 10?
Or can it be my Pen having issues?
