  1. Incorrect Blend Mode Appearance When Opening Illustrator 2024 File in Illustrator 2025

    I’ve encountered a potential bug in Illustrator. When I open a file created in Illustrator 2024 (version 28.7.4) in Illustrator 2025 (version 29.2.1), the appearance applied to the text does not display correctly.

    For example, in the attached file, the text at the bottom changes to a completely different design when opened in Illustrator 2025, which is causing a significant problem.

  2. Wireframe Conversion of 3D objects distorts the paths, straightens curves

    Converting 3D text to a wireframe often doesn’t show the curves of fonts correctly. During the process, these curves often turn into straight lines or rough shapes, losing the original look of the font or the 3D preview.

  3. Gaussian Blur Effect Changed in 29.1 from 29.0.1

    As previously reported in July 2020 when this happened with 24.2: https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/40865740-gaussian-blur-effect-producing-different-results-f

    This was last an issue with 24.2.3, and since 24.3 it had been successfully fixed with consistent results in 29.0.1.

    December 2nd, 2024: We have discovered that the issue is how the Gaussian Blur effect performs on Process vs Spot colours.

    In 29.1, Gaussian blur now produces an identical effect on both process & spot colours. We'd consider that a fix, as a designer should expect the same result no matter the colour used.

    The challenge here for Adobe is weighing "fixing the blur" vs customer legacy files.…

  4. 2025 (29.0.1) is giving tons of errors on preview.

    I have a file with some simple multi-gradient appearance stacks that constantly throws two errors every time I load it, and every time I switch outline mode on and off. Also the document is marked as modified the instant I load it.

    Works fine on 2023. Dunno how it works on 2024, I never switched to that one. Constantly complains on 2025.

    This is happening in CPU preview mode, I would check if it's happening in GPU mode as well but I deleted 2025 before thinking about that detail.

    Uservoice isn't letting me upload this file so I've posted it…

  6. Lighting preview is missing in 3D and Materials panel in Ai 2025, Undo does not work for 3D rotation, performance is slow

    Why is the preview for lighting missing? And why is the render so slow? Also why is there no undo option to take you back to the previous rotation position??!!!! This is Illustrator 2025! Horrible.

  7. Strokes on text area, fill disappear

    Not sure if this work as intended, but it seems a bug to me and it does not allow using text areas elements. and strokes.

    I need to apply a silhouette stroke to a whole group of elements.
    I add a stroke, and I move it as the last effect in the aspect panel. This work for every group of elements, symbols and etc. Expect with groups containing text areas with filled background. In this case infact the stroke is removing the color fill from the text area.

  8. 3D inflated art has rippled edges

    I'm getting rippled edges when I apply inflate to vector artwork. I've tried various settings but can't get it to appear as smooth lines. There's also a slight clipping to the right pupil. Can't get it to render properly.

  9. Gaussian Blur amount for the object dragged differs

    If you apply a Gaussian Blur effect to an object and drag it, Illustrator will change the value slightly and restore it back when the transformation is complete.

    It seems that Real-Time Drawing and Editing option does not apply the same amount of blur while the drag is in progress.

    Especially noticeable if you hide edges temporarily with Cmd/Ctrl + H.

    Increasing the blur radius makes the dragged preview blurrier, but still less than the intended value.

  10. 3D Crashing

    I have used 3D materials on my ASUS TUF Dash FTS for over a year with no prior issues. Last night, upon updating to version 28.1, every time I even click on the 3D materials menu within the window tab, it immediately stops responding and crashes. I have Uninstalled, reinstalled, reset preferences, cleaned up creative cloud, deleted almost everything on my computer and freed up an additional 100 GB of space (I have 600GB of space total), I have gotten rid of every plugin. I am just at a complete loss because I can now not complete assignments because even…

  11. Error al procesar la apariencia de objeto al momento de aplicar el efecto 3D

    Al momento de aplicar el efecto 3D a un objeto, me aparece "error al procesar la apariencia de objeto". Ya intenté volver a instalar Illustrator y otras sugerencias, pero el error persiste. Aclaro que antes si me funcionaba, y de un momento a otro dejó de hacerlo.

  12. Faulty upscaling of 3D object

    1. Windows 11 latest stable release
    2. Illustrator 29.9 (Desktop)
    3. I applied the 3D effect » Extrude & Bevel to my logo design then upscaled it to maximum size as I need exported large raster png of the logo design, but when I upscaled it it just couldn't handle the size as you can see in the attached screenshot below.

  13. Classic 3D transformations not working

    Classic 3D Transforms are working but acting weird. I created a square and tried to do a classic 3D Isometric Top Transform and it kind of worked, but it was as though it was missing a big triangle out of the front corner. I expanded the object thinking that perhaps it was a display issue and even the expanded version has the missing piece.

  14. Problems with Photoshop Effects

    Lately, everytime I try turning a vectored shape (after I gave it a gradient mesh) with no stroke, I constantly keep getting stray white pixels inside the stroke that seem to trace the stroke. I'm trying to make a quality illustration, but these pixels are keeping me from doing that. Thank you!

  15. Gaussian blur reverting when opacity is updated + blur effect creating a rectangular frame

    Gaussian blur gets disabled when you change the opacity of the shape; and will have to open the gaussian blur effect panel to re-apply the blur.

  16. Scaling appearance with Transform Effect doesn’t work as expected

    MacOS 12.6.3
    Illustrator 27.2

    Applying scaling transform effect with “Transform Objects” checkmark OFF
    and “Scale Strokes and Effects” and “Transform Patterns” ON
    doesn’t work properly in some cases, for example:
    irregularities in dash/gap lengths are introduced when scaling dashed lines,
    arrowheads are not scaled at all,
    pattern brushes are not scaled at all,
    art brushes are scaled partly (the unstretchable bits are not scaled while the main shaft is scaled).

    I would expect the same result as with Scale dialog box with the same settings — this one works perfectly. I want to replicate it as an appearance effect.

  17. Eyedropper random wrong results

    OSX 13.0.1
    Illustrator 27.1.1

    Attempting to pick up paragraph and character values of text with eyedropper. Test is built in a new document from a blank template, components pasted from a working file.
    Expected result: that selected text will end up with same values (font, color, size, lead, letterspacing) as sample
    Actual result: as far as I can see, completely random results. Sometimes the letterspacing is changed to a value neither the source nor the destination is set to. Sometimes nothing happens. In this video, the font color changes to a color that is not used in the document.

  18. Drop shadows rendering differently after updating from 25.0 to 25.4.4

    This is causing a lot of headaches in our department. The drop shadow appears to have gotten smaller after updating to 25.4.4, even though the values are the same. This edit is destructive and cannot be resolved by reverting to 25.0 and resaving. Attached is screenshot showing drop shadow changes. (AI file is larger than 50 MB.)

  19. 3D Revolve Classic not updating applied symbols after symbol changes

    Making changes inside a symbol does not update where it is used as an instance. Video below shows editing of an extrude with a symbol applied to the outside of a cylinder. The preview toggle on/off inside the extrude tool also does not work in updating the applied symbol in real time.

  20. GPU renderer fails on complex appearance stacks involving Knockout Group

    I have an appearance stack that uses a scatter brush at 0% opacity to knockout parts of the underlying fill, thanks to Knockout Group being checked on this object.

    It does not seem to work on the GPU renderer.

    Some experimentation suggests that it does work if I shift the overall object's transparency from Hard Light to Normal. I haven't tried other opacity modes.

    I have included a file with an example path, as well as screengrabs of how it renders on the CPU and GPU previews, and the data given by the "system info" button in the Performance pane…
