Random Lines Appear When Shading

I'm having issues where random straight lines appear during the process of shading with single lines, more specifically this seems to happen during the repetitive motion of drawing lines.

I'm using a Cintiq Pro 24 at 4K resolution. Here's an example. The lines highlighted by the arrows were randomly generated as I attempted to "shade"

Does anyone know the fix/workaround or root cause for this issue?
