Hi all
I'm running into this time and time again - I create solid color shapes or borders with tools like the cookie cutter, and they look extremely jagged / aliased. Pic 1 is a screenshot from a 4k project with circles done with the cookie cutter. They look terrible.The size doesn't change the issue.

Pic 2 is a circle downloaded from the internet. Look how smooth the border is.

What am I missing here? How can i get smoother lines and better definition?
Thanks!
