Can someone advise?

I have a shape, that is filled solid with black. It has reduced opacity.

It has a weird jagged stroke, evn though I dont have a stroke applied on it.

I have changed to different layer, and still shows. I have restarted all, and still shows.

Can someone advise?

So I figured out the issue. Due to the shapes in question belonging to a group, which were emanating from different steps in the creative process, there were multiple appearances within the group that were not matching according to the Appearance Panel, even when changing the Fill Color to the group as a whole. The solution I found was going into the group in Isolation Mode and clicking "Clear Appearance" in the Appearance Panel dropdown, and then selecting the entire group outside of Isolation, and choosing the desired color. This removed the odd stroke that was present in my previous screenshot. Thank you for your assistance and I hope this helps someone!

I think what you're seeing is a path rendering glitch on screen. If a path segment is bending between two anchor points in too much of an awkward or demanding way those rendering glitches can occur. I'll sometimes see errors like that when I'm manually drawing paths and adjusting the anchor points. Instead of the line stroke being uniform small portions of it will thicken and even flatten into a polygonal appearance. The glitches are just visible on screen; I haven't seen them print (my experience may differ from others). But the glitches are still disturbing to see. One solution to the problem is adding one or more anchor points along the curve between the two original anchor points. That will make it easier for the computer to render the path on screen.

Hi @Kristian230176518jp6,

 

We are sorry for the trouble. As Larry & Ton suggested, this should not be visible after switching to CPU mode. However, please check if you are seeing the strokes after exporting the file in PDF or JPG, or any other format. This is just a GPU preview/ rendering error on higher zoom levels which will not affect your output. If you are seeing this on exported files as well, then please share the Ai file with us. We will take a look at it and share our observations with you.

 

Kindly update the discussion if you still need assistance with it. We'd be happy to help.

 

Thanks & Regards,

Anshul Saini

Try switching from GPU Preview to CPU Preview. GPU Preview is fast but not necessarily as accurate as it needs to be.
