Problem with brush tool

[MelDeMay]

Hi everyone,

lately I've been experiencing problems with my brush tool. When I'm using the brush tool it creates solid dots at the beginning of a stroke at random occasions. It happens like every 2 seconds or so and I have no idea why. This is what it looks like. I just drew some lines next to each other to show what I mean:

I'm using a Cintiq 16 display withouth touch and am working on a Macbook Pro 13-inch 2019. I have macOS Catalina version 10.15.4 installed. I'm also using the latest version of Photoshop CC and  recently had to reinstall Photoshop and Adobe Creative Cloud, because of another problem that I've encountered. Before that the brush tool worked absolutely fine. 
I hope anyone can help me with this issue as it's driving me crazy while working on my paintings. 

Greetings
Mel

Does the issue also occur when wrking with the mouse? 

Does hiding the Rulers make a differences?

If I turn off the airbrush / build up feature on the brushes the problem seams to disapear
