Brush jumps back to a cursor arrow between strokes?

How do I keep the arrow cursor from appearing every time I lift my stylus? Drawing strokes and cross hatching is hard to focus with it jumping back and forth from an arrow to nib size or cross hairs of brush. It’s doing this with all tools. A constant flickering between the tool and an arrow. I’m not hovering over the UI, I’m trying to draw in the workspace. Using a macbook with a cintiq.

It’s having photoshop open. I found adobe illustrator users complaining about it and turns out, that’s the solution. Close photoshop.
