  1. Illustrator 25.0.0 breaks precision of metric units when working under custom created workspace

    When I create custom workspace and want to make new object, and when I type dimensions in the dialog box, Illustrator breaks dimensions, e.g. 250 mm becomes 250.5 or 250.06 or 249.999 or else. This also happens when I open previously created documents with exact dimensions, e.g its dimensions become broken.

    Note that this is happening only with custom workspaces created, and the problem persists even if I switch back to the default workspace. The only working solution is reinstalling Illustrator and working under any of the default workspaces, which is driving me nuts. Please fix it.

  2. Color Picker Selects White Instead of Black

    Very bizarre problem:

    1. I will create a new object using the pen tool.
    2. I select the Stroke Color icon and choose black for a border color.
    3. Illustrator will invariably select white instead of black. I will have to go back to the color picker and select black again for it to stick. Really irritating.

  3. Snap to point is not precise

    Snap to point is always pixels off, so "joining" doesn't work. Pen tool also won't connect to an anchor and will also be pixels off. Snap to point is turned on. Can't join points of lines and shapes to one another to make complete shape.

  5. Transform effect and Move dialog refuse to use negative numbers

    This has been a problem for a long time -- not just the current version of Illustrator. When applying a transform effect to an object and using the "move" part of the effect, negative numbers get converted to positive numbers. Occasionally I can "fool" the effect by not previewing the results but that doesn't work often. This happens whether I type in the numbers by hand or use the slider.

    Strokes become sporadic and missing in some places. I don't know what the issue is. My strokes were perfect yesterday and now I update my Mac and the strokes are now sporadic, jagged and missing in places. See screenshot.

  9. Opacity bug

    AI CC 2018
    I turned the opacity down on a selection to see below layers. Then I went to work on below layers. Upon returning to original layer and re-selecting the object to return it to 100% opacity it showed I was already at 100%. I could not get it back to 100% until I copied and pasted the object to a new layer.

    Hi,

    It seems like opacity is applied on the Layer and not on the object inside that layer. It is possible that the user is selecting object inside the layer and not the layer itself. Hence the user is able to see the opacity of object which is 100% in this case and not the changed opacity of layer.

  12. Illustrator insanely not optimized

    It's unbelievable that I have a 2025 recent PC, AMD Ryzen 9 9900X3D, 64Gb RAM DDR5 6200MHz, RTX 5070 Ti, M2 gen5 11500m/s and Illustrator 2026 is super slow, with a lot of lag when zooming in and out, the tools behavior also super slow. Honestly, the worst version so far.

  13. Using Image Trace with specific settings generates large black blob made of gigantic black circles

    Image Trace yields a black blob when adjusting the settings now. For instance, it renders a details drawing into a clump when changing the settings to have 1% for the corners slider. This bug is in AI 2026 only.

  15. Changes made by plugin tools are not rendered instantly in CPU Outline and Pixel Preview modes

    Just recently something changed for plugins, and changes these make don’t get updated in modes until you force the canvas to redraw (zoom, move, draw in the region... not pan though).
    Here, I try to use one of Astute Graphics’ plugins (it affects many) — I shorten the path, but Ai doesn’t re-render it!

    I bet it’s about performance, but come on! These tools is what keeps Ai afloat for many. Please don’t drop the support.

    Hi,


    Thanks for reporting this. At the moment, we’re unable to reproduce the issue on our end.

    To help us investigate further, could you please share:

    • The exact Astute Graphics plugin(s) installed (including version numbers)
    • The Illustrator version/build where you’re seeing the issue
    • Whether the issue is still reproducible in the latest CCD release build or the current beta build


    If possible, any additional details such as a short screen recording or .ai file where the issue consistently reproduces would be extremely helpful.


    Thanks for your help and patience—we appreciate you taking the time to report this.


    Best regards,

    Aishwarya

  18. Severe Lag in Adobe Illustrator When Editing Text and Objects—~15s Input Delay on 2MB File

    While working in Adobe Illustrator, I encountered severe performance issues across the entire application. Even with a lightweight file (~2MB), there was an approximately 15-second delay after any action—such as typing text, pressing Enter, or modifying objects. This lag affected not just text input but also general object manipulation and UI interactions.

    The issue persisted despite the file being relatively small. I’ve previously worked on significantly larger and more complex Illustrator files without similar lag. This suggests the problem may not be file size-related, but possibly linked to a software bug or compatibility issue.

    I attempted standard troubleshooting steps, including…

  19. Snap to Point doesn’t help much to snap an object’s edge to another edge, even with Smart Guides

    'Snap to point' in Illustrator is poor. You cannot currently snap objects together reliably. Results are inconsistent.
    For example:
    1) snapping a point to an edge does not work well, if at all. I have 'snap to point' on and smart guides enabled.
    2) when using constrain with the Shift key, whether they be points or edges. Even with Snap to Point turned on, or using Smart Guides. Just something simple as drag-copying another box adjacent to itself does not snap together the edges.

    In my videos, the first video applies to point 1) and the second video at 10s,…

  20. Objects vanish when a PDF is exported

    The PDF document is not being saved correctly. I have tried saving it in different ways, changing the elements and it still isn't working. I believe it is a problem in Acrobat itself perhaps?
