Why do pixels appear when using gaussian blur in illustrator?

Question

Adobe Illustrator

Hello, it happens that in illustrator you draw a shape with a pen or a simple circle, and when you try to blur according to Gauss, these shapes become pixelated. More precisely, at the edges of the pixels. But sometimes everything goes right. Why is this happening?

Answer 1

Well, just Illustrator is a vector editor, and Gaussian Blur, all of a sudden, is a raster effect. Try playing around with the Document Raster Effects Settings in the Effects menu and in particular increase the ppi resolution.
