  1. Calligraphic Brush, Blob Brush appearance anomalies at small brush sizes (1 pt and above)

    Illustrator 22.1, though this is extant in all versions I'm familiar with (since at least CS5).

    When drawing with a calligraphic brush (and thus also with the blob brush) at small sizes, certain tight curves result in anomalous shapes extending out from the expected area covered by the brush. The screenshot attached is around 15mm across. AI file also attached. Expected result is that the brushed area corresponds to the shape of the calligraphic brush along the whole length of the path.

    1. macOS Monterey(version 12.3.1)/Illustrator 26.3.1

    In optical kerning for many Japanese fonts,
    the space between characters is too narrow and some characters overlap.

    We have tried to address this issue in our beta build of 24.0.2.
    Please visit adobe.ly/1o2SDsg and get the latest build for version 24.0.2 (Build 1).

    Please do let us know if this issue is resolved for you or not.

    With Best Regards,

  4. ドロップシャドウの一部だけが解像度が低い

    macOS Catalina (Ver. 10.15.7)
    Illustrator 2021
    ラスタライズ効果設定の解像度が「350ppi」に設定されている状態で、複数箇所でドロップシャドウを使用しているファイルがあり、作業前はすべてのドロップシャドウが正しい350ppiの状態(表示)だったが、編集作業終了時に1箇所だけドロップシャドウの表示が、72ppi程度の解像度に変わっていた。
    色々と動作検証をしてみましたが同様の状態にできず、原因不明です。
    低解像度のドロップシャドウ部分は表示のみではなく出力した際も低解像度のままとなっており、ドロップシャドウ部分に変更を加えたり、コピペしたりすると正しい表示に戻るようです。

  5. Type on Path Characters vanish and appear scattered / exploded on far edges of canvas (when zoomed out) if outlined / expanded

    Started in in version 27.7.0
    Reproduction procedures:
    1. Create type on a path in document.
    2. Save the document and close it once.
    3. Open that document and select the text on a path.
    4. Execute command “Outline Text”

    The above procedure will make it all disappear and disappear.
    This phenomenon is not reproduced in Illustrator 2022 or earlier, so it seems to be a 2023-specific bug.

    再現手順
    1. ドキュメント上にパス上テキストを作成
    2. ドキュメントを保存し、いったん閉じる
    3. ドキュメントを開き、パス上テキストオブジェクトを選択
    4. アウトラインを作成

    以上の手順で、テキストはパスごと消えてなくなります。
    Illustrator2022以前では再現しなかったため、2023固有のバグと思われます。

  6. プリセットのB6サイズについて

    IllustratorのプリセットのB6サイズは125 mm×176 mmですが、日本の規格はB6サイズ182mm×128mmです。
    他の投稿より引用ですが、プリセットは、B4とB5はJISで、他のB系は国際規格になっているので、統一してほしいです。

  7. 「オーバープリントブラック...」の不具合

    OS/macOS11.6.8
    Illustrator.ver.27.7(以前のバージョンから同様の挙動と考えられます)

    スタイルの当たったテキストをCMYKの黒100でオーバーライドしたものに対して「編集→カラーを編集→オーバープリントブラック」を適用するとCMYK黒100の部分がスタイルのカラーにフォールバックする。

    再現方法
    1.テキストフレームを用意し塗りに対して明るい色を設定した段落スタイルを適用する。
    2.任意のテキストの塗りに対してCMY各0、K100のCMYKブラックを適用する。
    3.このテキストフレームを選択し「編集→カラーを編集→オーバープリントブラック」を適用する。
    4.CMYK黒で指定した部分は塗りに対してオーバープリントが設定されるが塗りがスタイルカラーに戻る。

    期待する結果
    「編集→カラーを編集→オーバープリントブラック」を適用してもスタイルを適用したあとでCMYKブラックをオーバーライドした部分の色が変わらずオーバープリント属性が設定される。

    実際の結果
    「編集→カラーを編集→オーバープリントブラック」を適用するとスタイルを適用したあとでCMYKブラックをオーバーライドした部分の色が変スタイルカラーに変わってしまう。

    回避方法
    スタイルを適用した部分を黒でオーバーライドする際はCMYKブラックではなくグレースケールのブラックを利用すると回避可能。

    また、スタイルが適用されたあとCMYKブラックをオーバーライドされた部分のあるテキストフレームをスクリプトにてoverprint属性を適用しようとした場合も同様にスタイルカラーに戻ってしまいます。

    回避方法がありますが、CMYKブラックとグレースケールブラックで挙動が異なるのは問題です。オーバープリントブラック処理は最終的に処理を行う場合が多い処理です。意図しない色変化が生じるリスクはできるだけ避けたほうが良いです。早急に改善いただきたいと思います。

    This problem is reportedly fixed in the latest Beta Build 30.5.0.18. You can update and test if it’s truly gone.

    However, please not there are some known issues with this particular build:

    • Opening recent files from Home Screen Recent section is not working (opening recent files from File > Open Recent Files works fine).
    • Generative Expand does not open its own HUD when used after Generate Vector, Generative Shape Fill, or Sketch to Vector. Instead, the previous tool's HUD is displayed and Generative Expand remains inaccessible. Workaround: Ungroup the generative content first, then apply Generative Expand.
    • Half of Astute Graphics plugins can’t get loaded. Both teams are now aware of the problem.
  8. Scale percentages are not consistent for images.

    When placing a file without changing the scale, the links panel should display 100%.
    It does that for Linked Tiff (and PSD) files, but displays a scale percentage (that depends on the resolution) for JPEG and PNG files.
    When images are Embedded, a scale percentage is shown, where a resolution of 72 ppi is shown as 100% and smaller percentages for higher resolutions.
    When images are just placed 100% should be shown, they are not scaled and their size reflects their resolution.
    Currently (Illustrator 28.7.1) it will show 100% for a Linked Tiff file with a resolution of 144 ppi,…

  9. Glyph substitution not working in v28.7.1

    In v28.7.1, if the formatting of the character immediately before a glyph substitution is different, the glyph substitution does not work, and the default glyph is displayed instead. This bug occurs just by opening an ai file from a previous version. It's an extremely serious bug.


    v28.7.1でグリフ置換が機能しない

    v28.7.1では、グリフ置換の直前の文字の書式が異なると、グリフ置換が機能せず、デフォルトのグリフが表示されてしまいます。このバグは、以前のバージョンのaiファイルを開いただけで発生します。非常に深刻なバグです。

  10. Character colors set for character/paragraph styles loaded from another document are lost when the file is saved and reopened.

    別のドキュメントから読み込んだ文字スタイル・段落スタイルに設定された文字カラーは,ファイルを保存して再度開いたときに失われてしまいます。

    1. macOS & Windows OS, Illustrator all versions

    2. 再現手順
      ① ドキュメント上で段落スタイルを新規作成し,文字カラーを設定後,保存する。
      ② 別のドキュメントの段落スタイルパネル「段落スタイルの読み込み…」より,①.ai を読み込む。
      ③ 読み込んだ段落スタイルを適用したテキストオブジェクトを作成し,保存する。
      ④ ③のドキュメントを再度開く。

    3. 望む結果:  ①で設定した文字の色が,段落スタイルの「文字カラー」に設定されている。

    4. 実際の結果:  段落スタイルの「文字カラー」は「なし」になっている。

    読み込んだスタイルを適用したテキストオブジェクトの見た目は黒くなり(カラースペースがDevice Grayになり),カラーパネルの表示は「?」になります。

    上記手順では「段落スタイル」について書いていますが,「文字スタイル」で設定した場合も,同様の不具合が発生します。

    2.問題が発生したときに実行していた手順
    Illustrator28.5以前で作成した添付の文字組み設定を、Illustrator28.7.1で開き、移動するなどすると前カッコが移動する。
    添付資料の文字組み設定を利用したテキストで、全角丸開始カッコのみ移動する。
    他の全角カッコでは問題なし。
    複数のPCで同様の症状が出る。

    3.想定していた結果

    as soon as i use Illustrator to draw using my surface pen on my surface 4 pro illustrator crashes. it did this to me in the trail of cc 2018 however i assumed it was because of the trail version. i subscribed to cc 2018 a few days ago to draw and i haven't been able to draw with my tablet. mouse seems to work but as soon as i use a brush with my surface pen it crashes and will not allow me to generate a crash report as it stays gray forcing me to restart my computer.

    Hello,

    Please accept my sincere apology for the inconvenience and disappointment the issue has caused. We do test our products thoroughly including running it through multiple beta testers and we really regret that this issue slipped past our quality checks.
    We have a fix and is available in the pre-release build. Please visit https://adobe.ly/1o2SDsg and get the latest build for version 23.0.5 (Build 2). While the build is prerelease this build is still of production quality. Please feel free to use/recommend it for your day to day activity.
    We would appreciate if you can give us the feedback on the correctness of the fix by pressing the Thumbs up button on the UserVoice page.

    Regards,
    Raghuveer Singh | Sr. Software Product Quality Specialist | Illustrator Team
    Creativity is all around you.

  14. MAJOR ISSUE: The new update does not let you decouple horizontal and vertical sizes!!

    The new update does not let you decouple horizontal and vertical sizes. I've unlocked them and toggled every possible option. Ex: I have a 3x5 shape, and want to make it 4x5. It will ONLY make it 4x6.7516 in. HUGE ISSUE.

    This was fixed in the Beta 30.8.0.7 and the team intends to push it into the next general July release.

    Meanwhile, please use the dedicated Transform panel or the Properties panel as a workaround.

    If you find anything else — please report and upvote, it really helps.

  15. Perceptual Gradients are uniformly converted to 72ppi images in PDF

  16. Image Map URL Links Disappear in PDF Export

    Issue occurs in Illustrator 2025 (29.6) and later versions

    Description:
    URL links configured through the Attributes panel’s Image Map feature are not preserved in exported PDFs, despite enabling the “Preserve Hyperlinks” option in PDF export settings.

    Steps to Reproduce:
    1. Create a new document
    2. Create an object (e.g., rectangle, text, etc.)
    3. Select the object and enter a URL in the Attributes panel → Image Map
    4. Create a new layer above the current layer
    5. Export as PDF with “Preserve Hyperlinks” enabled in export settings
    6. Open the exported PDF in Adobe Acrobat

    Expected Result:
    URL links should…

  17. Duplicate Graphic Styles

    Multipage document. Many objects with a specific style, rectangle, 20% gray fill, no line. All assigned graphic style, eg, Box Style. I want to move these objects to a new artboard, so it's select, Copy, Paste In Place, Move specific distance (because I've laid out my art boards precisely). Problem is that I then get Box Style 1, or Box Style 2, and so on.

    If I option drag this does not happen. This makes NO SENSE.

    Styles are styles. Why would Illustrator be duplicating styles. Makes NO SENSE. Option drag is NOT an efficient way for my workflow. Maybe…

  18. Color Mixer in Control and Properties panels gets broken after using Tab

    The Color Mixer in Properties and Control works oddly. Here, I try to navigate my fields with Tab, and then drag one slider — boom, it all breaks: sliders vanish, active fields become visually inactive, closing it becomes very hard...

    I feel like it started happening when the generative virus put its tendrils into Ai.

  19. Breaking links for several selected symbols at once doesn’t work

    At the moment it is not possible to unlink several selected symbols at once with the context menu command. Illustrator will unlink the symbol that is at the top in the layer panel.

    If you use the symbol menu command to unlink the symbols all selected symbols are unlinked.

    Thank you!

  20. Cambria text & large text cursor

    Looks like this was happening in 2017 as well... when using Cambria font, the cursor is 2 or 3 times as large as it should be when editing text. Makes highlighting & editing multiple rows almost impossible. I'd attach a file but others have shown the same thing already and it's simply a text box with Cambria text and a huge cursor. Text size is 11, height set at 13. In the same document but a text box using BonvenoCF, the cursor is the right height.
