  1. 塗りの線幅が縮小すると幅が変わってしまう

    図形や文字の幅をアピアランス→塗りを指定→パスのオフセットで
    幅を変更しています。v29.61と29.6でイラレを使用すると
    縮小などをした際に幅の比率が変わってしまいます。(線幅と効果拡大縮小もチェック済み)
    ※線で作成した図形や文字は比率を守ってくれます
    29.51を使用すると問題なく拡大縮小ができます。
    これはバグなのでしょうか?

  2. Files not saved properly with incorrect display

    Since we started working with Adobe Illustrator 30, we have encountered various files, both saved as ai and pdf, that display a different and incorrect image in the preview. As a result, our printing software also opens and processes these incorrectly, resulting in incorrect printing.
    When we reopen and resave the file, it is fine.
    For the time being, we have gone back to Adobe Illustrator 29, because we can no longer rely on our print file in this way.

  3. Not Getting "Overwrite notification" when exporting using "File/Export/Export as..."

    This only started happening recently and I'm not sure what to do to fix it. Whenever I export a file using the "Export as..." feature, I'll navigate to the location where it was previously exported and click the "Export" button. I used to get an overwrite notification asking if I wished to do so and I'd just click yes or no. Now, for some reason, that notification isn't triggering and Adobe Illustrator is just overwriting. I tried using Windows Explorer to copy and paste a file to the same location, and Windows "does" give the standard notification to confirm overwrite.…

  4. Real Time Drawing & Editing will not turn off for drawing shapes

    When I have Real Time Drawing & Editing turned OFF, shapes (rectangle, ellipse) still show up filled while drawing, instead of just the vector outline as expected.

    Steps to recreate:
    turn off real-time drawing & editing
    select random fill color
    select shape tool
    draw shape

    expected result: only vector outline is seen during drawing
    actual result: filled shape is seen during drawing

    I tested this and found the same behavior on both my Windows 10 desktop and my Windows 11 Laptop, both running Illustrator 29.8.1 (64-bit).

    There is no problem when moving an object, that still displays the vector outline…

  5. Scale strokes box keeps unchecking

    The "Scale Strokes and Effects" box keeps becoming unchecked making it necessary for me to check preferences for each document.

  6. Values in W / H fields in Transform dropdown from Control don’t get updated while editing another field with Constrain Proportions enabled

    When editing an object, click in the Height or Width input box and use the arrow keys on the keyboard to decrease the value. When changing one value (e.g. height), the other value is not updated. You must exit the window and return to it to see the value.

  8. Dotted Guides are not precise in GPU preview

    Guides should allow us to be sure about alignment.
    And while in CPU it’s mostly true, in GPU preview dotted guides get drawn 1 pixel off.
    These should perfectly overlap the edges of the object aligned!

    Look at the GIF attached

    If you notice a bug with the bounding bounding box not getting displayed when I select the rectangle in the CPU Preview mode — it’s a separate Beta-only bug, reported here: http://illustrator.uservoice.com/forums/939477/suggestions/50759876

  9. Circle with thin stroke aligned inside has artifacts in GPU Preview

    I’ve noticed that when I draw a circle with a diameter of 250 mm and a stroke thickness of 0.25 pt, with the stroke alignment set to inside, and then draw another circle with the same stroke thickness but a diameter of 230 mm, the smaller circle shows irregularities in the stroke line (see images).

    When the stroke alignment is set to center, however, the circle is displayed correctly.
    This issue isn’t serious, I just noticed it while working.

  10. アートボード左上の角に丸が表示される / Brush tip shape appears in top-left corner of the artboard

    再現手順
    1. Illustratorを起動して新規ドキュメントを作成する
    2. ブラシパネルでカリグラフィブラシのサムネイルをクリックする
    3. アートボードの左上の角を確認すると、ブラシの先端形状の丸が表示される

    回避策
    - ブラシツールに切り替えてからカリグラフィブラシのサムネイルをクリックすると丸は表示されない
    - 丸が表示された後でも、ブラシツールに切り替えると消える

    一度でもブラシツールに切り替えれば、その後はIllustratorを終了するまで、新たな別のドキュメントを作成してもこの丸は出現しません。

    • MacOS14(Sonoma)+Illustrator2025(29.5)で確認
    • Windowsでも同様の手順で再現するそう
    • これまで再現条件が分からず報告出来なかったが、2022年の時点で既に発生しており、現在まで改善されないままである

    表示が煩わしいのみで特に大きな実害はありませんが、さらに古いバージョンでは発生しなかった不具合です。できるだけ早い解消が望まれます。


    Steps to reproduce:

    1. Create a new document in Illustrator.
    2. In the Brushes panel, click a Calligraphic Brush thumbnail.
    3. A round shape appears in the top-left corner of the artboard.

    Workaround:
    - Switching to the Brush Tool before clicking the brush prevents this.
    - Switching to the Brush Tool after the shape appears will remove it.

    After switching to the Brush Tool once, it won’t appear again during the session.

    Notes:
    - Reproduced on macOS 14 (Sonoma) + Illustrator 2025 (v29.5).
    - Also confirmed…

  13. Exclusive to Mac Version: Lines Appear in PDF/x-4 Files, Not Present in Windows Version

    When placing a compatible PSD file (*1) into an AI document and exporting it as PDF/x-4, there has long been a bug where black lines appear on the edges of transparent areas. This issue has been fixed in the Windows version, but it remains unresolved in the Mac version, even in version 2024.

    The issue does not occur in the Windows version, even with the same version of Illustrator. It only happens on the Mac version.
    It occurs whether the PSD is linked or embedded.
    Even if an AI file is created on Windows and has no problems in the…

  14. Picking Eyedropper temporarily disables Smart Guides

    As reported here: https://www.reddit.com/r/AdobeIllustrator/comments/1p6ecuj/behavior_of_eyedropper_tool_changed_recently/

    In previous versions (can’t say for sure now when it stopped) we were able to aim with the Eyedropper better, when Smart Guides were enabled. In CC 2017 it works. Was quite helpful to pick color from a stroke, highlighting the object that is going to be sampled. Cool, right?

    But now, I suppose with the Photoshop-style sampling rings glued on, Illustrator forgot it’s a vector program. The sampling ring should not disable Smart guides!

    I somewhat get why pressing Shift might disable it, because Shift enables the 'sample by pixel' mode, and picking a color…

  15. フォントの表示がおかしい

    本日Illustratorのアップデート後、作成途中のドキュメント上のほとんどの文字が正常に表示されなくなりました。例えば、文字間の詰めが-1000のようになっている(数値は0なのに)。漢字が図形に化けている。書体によっては、まとなものもありますが、メインで使う新ゴやリュウミンなどは全く表示されません。
    ところが、フォントの表示がないのに、PDFにすると表示されているのはなぜでしょう。

  16. Centre Points of all objects are visible when I reopen files

    Illustrator 30.0 on Mac Ventura 13.7.8

    Each time I reopen a file in which I had a mix of objects with either visible or hidden centre points, most of these are visible (at least, those of paths, guides…) and they can get in the way.

    I think this started happening with the new version 30.0 (or maybe just the one before).

    Here are examples of 2 similar files, one with and one without all Centre Points showing.

    The team tried to fix this in Beta 30.1.0.109. The latest one is 30.2.0.12.

    If you can — please try to use Beta and see if no centers will be enabled or disabled when reopening a file. The fix won’t remove those that are already in a document, so we need to to toggle them manually in the Attributes panel.

  17. Phantom objects in Finder Preview and when imported into Photoshop

    I'm on MacOS. When previewing an .ai file in Finder, there will often times be phantom objects visible in Finder Preview. These objects are always duplicates of whatever is actually visible on the artboard-- usually it's a phantom object in the position the object was in the last time I saved the file. When I open the .ai file in Illustrator, those objects do not exist. The objects are not hidden; they are not on some other layer. This is particularly problematic because those phantom objects are still there if I open the .ai file in Photoshop. If I add…

  18. Spot swatch color is not saved correctly when changing the color of an existing swatch

    1. Details of your operating system: Microsoft Windows 10 Pro (10.0.19045 Build 19045)

    2. The version of Adobe Illustrator (desktop): 30.0

    3. The steps you were taking when you experienced the issues:
      Create a new document, add a spot swatch and set the color to 100% cyan (or any color). Apply this spot swatch to an object, like a rectangle for example. Save the document as an .ai file. Then, change the color of the spot swatch to a different color (for example 100% yellow, or any color). Save the document again as an .ai file. Open the document in Acrobat.

  19. 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.
