I'm having trouble with the brushes. When I try to use my tablet and stylo my brush strokes create this gooey dotted line affect that makes what should look like a clean brush stroke look actually like a long pearl necklace made of black pearls. No matter what I try to adjust on my tablet settings or on the pressure settings in the Krita program it stays the same. I'm trying to draw comics and while it would be funny to see characters made of black pearl necklaces the joke would get old easily after the first page. Mark my words, nobody should have to sit through a comic stuffed with black pearl necklaces.
I'd be grateful for any help.

What is your OS? What brand of tablet are you using? Which version of the drivers for that tablet have you installed? Which version of Krita are you using?

OS: Microsoft 10
Tablet: I think it's called an "XP-PEN ARTIST 12". it's a drawing tablet with a screen on it
Krita Version 4.2.9

Then you will have to experiment with different driver versions. This problem has been reported before, and according to the reporters the problem went away when they installed a different driver version. I don't have access to the hardware, so I cannot experiment myself.
