Sean, sorry it took it so long to answer.
I suspect that the problem is about GPU rendering, because it is known to produce faster results with some tolerance in calculations.

The thing you are referring is called an edge, right? You can also disable them by Ctrl+H.

So, please:
1. Try to disable GPU (Ctrl+E by default) it and check if it gets better
2. Attach a file and and the screenshot of exact area of it for the team to check

the fill of the object is not following the curves. It's seems to be the preview in Illustrator because when I paste it in Photoshop it displays correctly.

This is STILL an issue if anyone reads this.
I'll take another stab at describing the issue:

If I draw a wave, there is a neon green outline(smart guide) and black color fill with no stroke.
When zoomed in to maximum value - the color fill varies by coloring outside of the lines and/or not making it all the way to the lines. This affects trimming overlapping shapes and creates arbitrary artifacts. This is affecting our print accuracy and work flow. Adobe, please contact me if you have any questions! The quicker this can be corrected the better. Thank you!

is there anybody out there?

will there be a response to this?

^Bump^ still happening

did this help explain it?

No problem. I use the pen tool to create a shape, then as you can see in the photo, the color fill goes beyond the line drawn by the pen tool. I may be wrong for calling this line a smart guide. Sometimes the error is more off than other times. Thanks

Sean, I guess it would help a bit if you tell how exactly you create or move these shapes and how do you use guides in it. It's not obvious :)

Color Fill is not inside the smart guides. It has been happening more and more often. I do not know if an update has changed a setting or what. Color is filling outside of the guides and it is making our screen printing seps take longer and longer to go in an visually align everything. not to mention creating an underbase taking longer due to having to fix areas where colors are overlapped or not overlapped. running 23.0.1

After last update, the edges of selected objects seems shifted compared to shape outline about 1 pixel, while anchor point is centered.
When zoomed it's not well visible, but with small objects it's very annoying.

Hi Carina,

I did not understand the issue. Are you trying to say that filling of color in the shape is not correct.
