Is There a Way to Fix Non-Continuous Grease Pencil Strokes?

I’m interested in using Blender as a 2D animation program with the Grease Pencil as I’ve seen online. However, when I draw thick lines using this tool, I get a strange result.



The problem is even worse when zoomed out.


As you can see, I get multiple closely packed line segments instead of a clean, continuous line. This will not work for anyone who wants to get clean fluid lines for inking animations in Blender. Does anyone know how to fix this?
