  2. 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.

  3. 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…

  6. 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…

  7. 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。

  8. 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…

  9. Live text converts to outlines when copying and pasting within Illustrator

    When copying artwork that contains live (editable) text and pasting it within the same document, or between Illustrator documents, the text objects intermittently convert to outlines (rendering them non-editable). This occurs with both area type and point type.

    This is happening with brand new files (not old ones). Dragging from one Illustrator document to another (correctly) brings in editable text, but I've ensured no third-party clipboard managers are enabled.

    保存されたSVGファイルをIllustratorで開くとテキストはすべてアウトラインに変換されており、

    望まれる結果:

    ----Translation----
    It may differ from the actual terminology. Sorry.

  11. 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

  12. 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

  13. 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.

  15. Can't select linked png/bmp files when they have transparent backgrounds.

    Placing several linked BMP or PNG files with transparent backgrounds causes them to become randomly unselectable by clicking on them. You have to go to outline mode, find and select the edge of the image, or select with marquee tool and then carefully unselect the extra objects. Either way, it cannot be moved except to click on the edge of the images frame. This has been an issue for years. I think I may have even posted about it before, but can't find that now. IMO this is an issue that should be escalated as it such a basic operation…

  18. Can’t edit colors in a selection

    When going to edit a color CMYK mixture the mixtures go blank and then it acts as if their is no fill color. I am trying to edit the CMYK mix to match the PMS mix and it keeps glitching after my latest update. You can see in my image that even though the color is slected it shows no color in the fill or a question mark.

  19. Rasterizing an object inside of a clipping group flattens the clipping group itself

    If we need to rasterize one selected object inside of the clipping group, we have to isolate the object to avoid flattening the clipping group. Isolating only the clipping group won’t help, we have to 'drill into' the object specifically!

    This doesn’t happen for simple groups — with these we don’t have to isolate anything at all, just selecting a child is enough.

    Thanks to Junior Rocha for raising this up.

  20. Illustrator最新版で A-OTF フォントが使用できない件について

    お世話になっております。

    現在、以下の環境で A-OTF フォントが Illustrator で使用できない 不具合が発生しております。

    環境

    macOS:15.6.1(Sequoia)

    Adobe Illustrator:最新版(28.x)

    Morisawa Fonts アプリ:最新版を使用

    フォント例:A-OTF ゴシックMB101 Pr5

    症状

    Illustrator のフォント一覧には A-OTF フォントが表示されるが、選択すると代替フォントに置き換わり使用できない。

    Photoshop など他の Adobe アプリ(Photoshop、InDesign)では同じフォントを正常に使用可能。

    Morisawa Fonts アプリ上では該当フォントはアクティブ化されている。

    実施済み対策

    Illustrator のアンインストール/クリーンインストール

    環境設定・キャッシュの削除

    Morisawa Fonts アプリの再インストール、ログイン/再アクティブ化

    macOS 再起動

    上記すべてを実施しても改善せず

    特記事項

    Illustratorを一つ古いバージョン(27.x)に戻したところ、問題なくフォントを使用できた。

    よって、最新版 Illustrator(28.x)と macOS 15.6.1 環境における A-OTF フォントの不具合である可能性が高いと考えられる。

    ご確認いただきたいこと

    Illustrator最新版と macOS 15.6.1 環境での A-OTF フォント非対応/不具合について既知の情報があるか

    修正版のリリース予定があるか

    回避策があればご教示いただきたい
