Very pixilated drawing strokes in different layers

[defaulta858mo6ojfsl]

I have a soft round brush and my strokes are very pixilated for some reason, does anyone know a fix, I have the most updated PS. I've narrowed the problem down to when a new layer is created and it's only visible when the underlayer is hidden.

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue? 

Does turning on »Deactivate Native Canvas« (Photoshop > Preferences > Technology Previews) and restarting Photoshop have any bearing on the issue?
