Curved paths not honouring guide styles / Guides are not dotted
When converting artwork to guides, anything that has a curved path does not show the guide style set up in preferences. In my case I have guides set up as a dashed line with a light grey colour. What I'm seeing is a solid black line. Happens in AI 29.6.1 and the beta 29.7 88. Sample shows two shapes converted to guides but the ellipse remains as a solid black line. Using MacOS 14.7.6.

Same problem here, as GPU is switched on , curved guides are displayed as solid lines

Thanks for your response Egor. I've attached a sample file. Maybe, I did something wrong with my preferences at some point?
I am using Illustrator 29.8.1

Illustrator "guides" are displayed differently for curved versus straight lines. Curved lines are appearing solid and straight lines dotted. My "guide" preferences are set to "dotted" for everything. Any ideas?

We're at beta 30.0 4 and still not addressed. Having to use v28.7.9 until this is fixed.

This applies to all files.
When the option to select guide type (in preferences) is selected as dotted lines the lines do not become dotted. This means it is very distracting when trying to use guidelines as they look the same as the artwork.
Essentially, switching to "dotted line" for guides just doesn't work. -
I confirm this. Happens only with curved paths and only with GPU Preview mode.

Wow. Doesn’t happen for me, a dotted guide stays dotted...
Cant you share a test file, please, just in case? Are you on 29.6? Does it behave the same in Beta 29.7.0.23? -

All of a sudden, any path that is rounded makes a solid guideline and any straight path makes a dotted guide.
Is this new?
FYI, I have always set my guides to be dotted lines.
