Hi, thanks for the report. I can confirm it locally.
Issue happens when faces are smooth shaded and Auto smooth is active in object data properties tab.
2.93 is last working version AFAICT.

Hi!

It's actually not an issue, there's just another option under geometry processing "Crease on smooth" needs to be turned on:

This option is in place so it makes it more robust working on smoothed surfaces where in a lot of use cases (especially in manga/anime etc) a whole object is smooth shaded and making this as default prevents those lines showing with a global crease-threshold.

I'll add this to my notes, it should be more obvious for later line art designs...

I think I'll close this for now as well :)

I got it now. But it's really a bit confusing for artists.
Maybe you should add some examples in the manual or bascally revise the blender manual for this topic.

Thank you for your feedback!

@ChristophWerner This feature is added a bit later, so the manual isn't getting quite up to date... Will make sure in the future.

There're several grease pencil LineArt topics not included in the manual. :)
