  1. GPU rendering & mouse with indents (stepping) scroll wheel = blurry graphics

    When scrolling with a scroll wheel that has indents, the GPU rendering causes blurry graphics at the beginning of the newly rendered pars that come into the workspace. See attachment.
    It takes half a second to render that portion of the screen in normal quality on a Mac Studio Max! This machine should render fast enough to see no blurry parts. (120fps games as an example!)
    I suspect Ai 29.8.2 to have a render engine problem. It’s just too slow. Other apps like Figma, Affinity Designer render the same documents 100x faster.

  2. Pencil tool preview not showing

    Hello, in illustrator 29.4 and 29.5 (on windows 11 pro) I can't preview the path while i am drawing with the pencil tool. I checked all the settings and everything is set to see it. I had to downgrade to illustrator 29.2 to use it again

  3. Suffix still gets added when an image is exported even though the option to add it is disabled

    While exporting a AI file to, for example JPG, the checkbox for automatic file extension (suffix) is unchecked. When I export it, the filename gets a extension (suffix) '-01' behind it. When I export, check the box, and uncheck it, the file saves without the extension (suffix), like it should. So every time I have to check and uncheck the option before exporting. Very annoying. Never had this issue before.

    Newest updated installed 29.6.1 on Windows 10 Pro.

    Anyone else has the same issue?

  4. 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?

  5. 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.…

  6. 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…

  8. 「環境にないフォントを解決する」などからバリアブルフォントをアクティベートできない/Cannot activate variable fonts through Resolve Missing Fonts.

    Adobe Fontsが含まれたドキュメントを開くとき、そのフォントが環境になくても「環境にないフォントを解決する」などからアクティベートできるのですが、バリアブルフォントの場合はアクティベートができず、困っています。

    ・和文でも欧文でもバリアブルフォントだとアクティベートできない
    ・Beta版と製品版(2025、2024)で確認したが、アクティベートできないのはいずれも同じ

    回避策として

    ・Adobe FontsのWebサイトで事前にアクティベートしておく
    ・文字パネルの「さらに検索」タブからアクティベートする

    などの方法が挙げられますが、単純に手間ですし、初心者さんにとってはハードルの高い作業だと感じます。
    ほかのフォント同様に「環境にないフォントを解決する」や「フォントの検索や置き換え」からでもアクティベートできるのが正しい挙動だと考えています。

    UserVoiceで似たような報告を見つけられなかったので、日本語版だけのバグではないか?と疑っています。
    バグであれば早めに解消いただけると嬉しいです。


    When opening a document with Adobe Fonts, missing fonts can usually be activated via "Resolve Missing Fonts," but variable fonts cannot.

    • This affects both Japanese and Latin variable fonts.
    • Tested in Beta and release versions (2025, 2024) with the same result.

    Workarounds:

    - Manually activating fonts on the Adobe Fonts website.

    - Using the "Find More" tab in the Character panel.

    However, these add extra steps and can be difficult for beginners. Variable fonts should also be activatable through "Resolve Missing Fonts" and "Find/Replace Fonts," just like other…

  9. 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.

  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…

  11. 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.

  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. Illustrator no longer keeping custom layer colors. Layer colors revert to black

    In recent Illustrator builds, custom layer colors applied to layers are not being saved with the document. When reopening the file, all layers that used custom colors revert to black, regardless of the original assignments. Default layer colors still persist correctly.

    Steps to Reproduce:
    Create a new Illustrator document.
    Add multiple layers.
    Assign custom RGB colors to the layers (not from the default layer color list).
    Save and close the document.
    Reopen the document.

    Expected Result:
    Layers retain the custom colors assigned to them.

    Actual Result:
    All custom-colored layers revert to black, while default colors are preserved.

    Impact:
    This breaks…

  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。

  17. 縦組みのエリア内文字のスレッドテキストオプション作成が正常に機能しない

    macOS 14.7.2
    Illustrator ver.29.1

    Step to reproduce
    1.縦組みのエリア内文字を作成する
    2.矩形ツールで矩形を描く
    3.エリア内文字と矩形を選択してメニュー「書式→スレッドテキストオプション→作成」を選択する。
    4.矩形が縦組みエリア内文字に変換されるが、スレッドテキストにはならずエリア内文字のコンテンツがコピーされた状態になる。

    期待する動作
    矩形がスレッドテキストとして正常にリンクされる。

    実際の結果
    スレッドテキスト→作成を実行してもスレッドテキストとならずコンテンツの状態もおかしい。

    回避策
    Tツールを使って手動でスレッドテキストをリンクさせる。

    縦組みに対するスレッドテキストオプションの挙動は全般おかしく、エリア内文字や矩形の構成や状態によって挙動が異なる場合がありますが、全般的に意図した通りに動作しない。
    また、おかしくなったエリア内テキストを手動でリンクさせようとするとIllustratorがクラッシュします。

    以下のコミュニティ投稿もご参照ください。
    https://community.adobe.com/t5/illustratorフォーラム-discussions/縦書き文章でスレッドテキストオプションが正常におこなわれない/td-p/15077023?profile.language=ja

  18. More than 1 Placed Item that has been named loses name in 29.6.1

    Place 2 linked items. Rename each item in the layer panel to Item 1 and item 2. Save File as Template or Document. Reopen. Only the first name appears. The second appears as <Linked File>. Any others also are renamed to <Linked File>. This is crucial to automation of template files to replace linked files and needs to be fixed! Have no issues with 29.5

  19. File names are broken on macOS scripts

    Bug reproduction:

    #target illustrator
    
    var file = File.openDialog("Select any file", "All files:*.*");
    var message = 'Results\nfile.name: "' + file.name + '"\nfile.displayName: "' + file.displayName + '"\nfile.localizedName: "' + file.localizedName + '"';
    alert(message);
    

    Save this as a script, run it in Illustrator on macOS and select any file.

    Expected outcome: An alert is displayed with all of the name attributes are populated
    Actual outcome: displayName and localizedName give empty string and undefined.

    Tested on macOS 15.7.1, Illustrator v29.8.2. Same script works on Windows 11.
