Hi there,
I'm currently having an issue where every digital drawing software I use makes the lines I draw very jagged, the only one i've found that doesn't do this is fire alpaca which doesn't have the brush options I want for painting, i've tried using Krita because of it's brush engine, but if I try to draw a circle or even just curves it brakes it down into a bunch of straight lines.

Not sure what I can do to fix this so any help would be good.
Thank you.
