Hi! I've experienced a problem with Gaussian blur. As you can see below on my screenshots when I put Gaussian blurred shape(circle) on top of the white shape(rectangle) it looks diffrently from what it looks like just on an artboard. It's the same circle with Gaussian blur copied and pasted.

Can somebody help me fix it?

Hi Elena, I tried to do it on Illustrator, I have the same comment as you. But when I exported it (to JPG and PDF), the problem is no longer. This leads me to understand that this is just a slight display difference in Illustrator and will have no impact on the exported project.

Make sure the values are high enough and add around object enough to not clip/

I have the highest resolution (300 dpi), Background: transparent, preserve spot colors are turned on and the add around object is enough. What should I change?

If you put the same blurred circle against similar filled gray rectangle it would look the same as against the gray pasteboard.

Thanks for your help! I've already received an answer that solves my problem.

However, I'm not sure if I understood you right. I should create a gray rectangle with a color similiar to the pasteboard, right? I just don't undestand how does it help? Maybe I've done something wrong.

The difference disappears when you change the background.
