Invisible Filling Bug (with pictures!)

[Vector Oriole]

Hello,

I came across this weird bug. Illustrator keeps adding "invisible" fillings to paths.

This is the outline view, and the original lines :

And this is the GPU view.

If i expand it, the "invisible" filling becomes an actual (false) path, so the issue isn't limited on the preview.

Any ideas?

Those are calligraphy brushes, right?

Something like that. But the issue isn't limited on one tool, it occurs on shape-builder as well, or after an action with pathfinder

Check your Properties Panel for Brush option:

I'm confident it is not a Brush option.

It is NOT consistent, the brush simply shouldn't appear like that. Also, like i mentioned above, the same exact issue occurs on other occasions, like when merging shapes with shape builder. It appears like a small "filled" shape on corners that has no reason to exist there.

It's a long known issue with calligraphy brushes.

Paintbrush bug - curves filled in?

I've had this issue before too.

If you outline your paths or do an expand on the path where you see that object glitch, does it stay or go away upon conversion? Usually for me it goes away unless I'm using a custom brush type. I sometimes see it with Brush Profiles even though I'm not using a brush on the stroke.

Thanks, good to know others have this issue too.

At this exact example, that line stayed even after i expanded. Other cases are less destructive, like filling a corner of a shape after using shape builder.

Please read the link I posted above. It also contains the solution.

By solution you mean the Zig Zag effect thing? Or am i missing something else?

[Monika Gause]

The zig zag effect usually solves the issue with calligraphic brushes, yes.
