Bounding box center markers disappear when dragging a guide.
I'm trying to position a guide over the center of a vector object. However when I grab the guide from the ruler, the bounding box center markers disappear making the task impossible. This wasn't always the case but I don't know when it changed. The bounding box stays intact but the horizontal and vertical center boxes disappear when I pick up the guide.

Swatch pattern reduces scale when copied from one illustrator document to another
When I copy a CAD drawing from one illustrator document to another, the pattern swatch scale in the CAD reduces.
I've noticed it doesn't happen with every swatch, only some. Sometimes the CAD itself will also reduce scale.
I have also noticed that if I create a new document I won't have this issue, however when I paste it into an already existing document, this is when the problem is usually occurring.
I have doubled checked the canvas size for both documents, and they are the same.
This is in version 30.2.1.9 votesWe have this issue fixed in our latest release - v30.3
Please update your Illustrator to this version and try it out.

Acrobat layers duplicate excessively in AI file’s compatible PDF
Illustrator 2025 (29.8.2)
When “Save in Background” is enabled, the Acrobat layers in the compatible PDF within AI files duplicate according to the number of artboards. For example, when there are 10 artboards and 2 layers, there should be 2 Acrobat layers, but instead 20 layers are generated.
aiファイルの互換PDFでAcrobatレイヤーが過剰に複製される
「バックグラウンドで保存」が有効な場合、AIファイル内の互換PDFにおけるAcrobatレイヤーがアートボードの数に応じて複製されます。例えば、アートボードが10個、レイヤーが2個ある場合、Acrobatレイヤーは2個であるべきところ、実際には20個のレイヤーが生成されます。

Pasting a single CMYK channel value modifies all CMYK channels
Illustrator version: 29.8.9
Operating System: Windows 11Description:
When I copy a single CMYK percentage value (for example, the K/Black percentage) from one object using the Color panel and paste it into the corresponding CMYK field of another object, Illustrator also changes the other CMYK channel values automatically.Expected result:
Only the pasted CMYK channel (for example, K) should change, while the remaining CMYK values should remain unchanged.Actual result:
Illustrator modifies the other CMYK channel values as well, even though I only pasted a value into a single channel.Question:
Is this the expected behavior (a feature), or is…3 votes -
优化运行内存占用
- Adobe Illustrator 2026 (version 30.7) consumes excessive memory upon launch—just enabling it uses up to 900MB.
- A file with 80 artboards, all containing text, sized at 263mm wide by 359mm high, experiences lag when dragging 5 or 10 artboards; there is noticeable delay. After creating outlines for the text and clicking X to exit, the software crashes.
- Saving a document with 80 artboards as a PDF does not allow background saving.
- A file with 110 artboards, each 263mm wide by 359mm high and filled entirely with text, causes extremely high memory usage. Copying and pasting operations are sluggish. We request…

Thumbnails glitching when saved
Randomly, when files and thumbnails are saved out of Illustrator, the resulting thumbnails are glitched in a variety of ways. This glitch is present in the preview in the Finder window, but upon opening the file again, the glitch is not present. This is not from appearances or overprint being applied to artwork elements, as we are familiar with the issues those settings present in a print production environment, and this is a separate issue.

テキストボックスのリンク テキストの内容が重複するエラーが起きる
Adobe Illustrator 30.8.1で同様の現象が発生しています。
日本語の縦書きで、エリア内文字のテキストボックス同士をリンクして使用しています。
作成直後は正常に文章が次のテキストボックスへ流れていますが、編集作業や保存を続けていると、1つ目のテキストボックスの内容が2つ目のリンク先テキストボックスに重複して表示されることがあります。
重複した文章によって、本来2つ目に入っていた文章が後ろへ押し出され、オーバーフローも発生します。
制作途中では正常に見えていても、編集・保存後に突然文章が重複するため、印刷物などの実制作では非常に危険な不具合です。

Offset Path creates notches
Certain paths with certain Offset Path values create these.
Usually it’s a rather small value, but this sometimes happens with larger ones.There are other related problems with Offset Path:
1. Stroke displaying incorrectly and Offset Path broken — http://illustrator.uservoice.com/forums/601447/suggestions/39059872
2. Offset Path with small values (or Inside / Outside strokes) results in skewed lines — http://illustrator.uservoice.com/forums/601447/suggestions/3942595918 votes -
New Blend panel doesn’t support actions
As reported by Kurt Gold here —https://community.adobe.com/questions-652/illustrator-30-7-new-blend-panel-no-actions-1635013
In Illustrator 30.7 the modal Blend Options dialog was replaced with a dedicated Blend panel. Basically, that's an improvement.
BUT: Unlike the modal dialog, none of the settings in the new panel can be recorded as part of an action in the Actions panel. That's a pain.
Adobe, I guess you can imagine that this is a serious setback for action creators?
What is the general reason why you don't make sure that new commands/settings are always actionable?

Hidden Characters remain visible when exporting in PNG
Windows 11 Pro Version 25H2
I work with Hidden Characters on, and when I export a PNG (export for Screens), they remain visible. Hidden Characters aren't supposed to remain visible after a PNG export. The only way that I could resolve the issue is to turn them off. But when I try to disable hidden characters, it looks like they are already off (even though I can still see them), and I have to turn them on, then off again, to make sure they are completely disabled.

Un-tabbed document (i.e. dragged out of application frame) jumping to font
Mac OS Tahoe 26.5.2
Illustrator 30.6Fairly recent issue following a Mac OS update.
I have a number of documents open/tabbed in the application frame.
I drag one out of the application frame in order to work on it while conveniently being able to view another document in the application frame behind.
I click on the document in the application frame to make an adjustment and the un-tabbed document jumps in front.
Repeatedly clicking the document in the application frame does eventually give it focus but the un-tabbed document will always randomly jump to the front without me clicking anywhere…

Illustrator 30.3+ silently substitutes installed fonts without reporting them missing (prepress risk on macOS)
This is reproducible with a single existing AI file by opening it in 30.2.1 and then opening the identical file in 30.3+ on the same Mac without changing any fonts.
Starting with Illustrator 30.3 on macOS, Illustrator silently renders some installed fonts as Myriad while continuing to report "Missing Fonts: 0." This creates a serious prepress issue because converting text to outlines permanently outlines the wrong font with no warning.
I am using Monotype Connect Fonts to manage fonts.
Versions tested on the same Mac with the same AI file and same font environment:

Inconsistency With Transform Controls in Control Bar
I am noticing inconsistent display of Transform dimensions in the Control bar, when selecting similar elements. Referencing the attached images, notice that when one of the pasted .tif images is selected, the Transform dimensions are displayed in the Control Bar, but when the other image is selected, the Transform controls are collapsed and require an extra click to view and copy/paste sizes. These images were copy and pasted from the same website and appear to be the same format. Unfortunately, this slows down my workflow as previous iterations of the software always displayed the Transform dimensions of selected elements within…

エンベロープにしたオブジェクトを極端に拡大すると結果がズレる/Envelope Distort becomes misaligned at large scale
問題の説明:
エンベロープにしたオブジェクトを極端に拡大すると結果がズレる再現手順:
1. ドキュメントを作成してオブジェクトを描画し、適当なカラーを設定する
→長方形や楕円形など、何でも良い。確認しやすくするため、小さめに作ると良い
2. オブジェクトを選択し、「オブジェクト」メニュー→「エンベロープ」→「メッシュで作成」を実行する
3. ダイアログで好きなメッシュ数を設定し、エンベロープを作成する
4. 出来上がったエンベロープを選択したまま、3000~4000%など大きなパーセンテージで拡大する。
→バウンディングボックス、拡大・縮小ツール、変形パネルでの数値指定など、拡大の方法は何でも良い実際の結果:
特定の大きさを超えると、エンベロープ内のオブジェクトがメッシュからズレた大きさで変形される期待された結果:
どれだけ拡大してもメッシュに合わせた大きさでエンベロープ内のオブジェクトが変形される回避方法:

Illustrator 2026 embeds each duplicate bitmap image separately in PDFs, causing extremely large files
Mac Studio M2 Ultra, Tahoe 26.5.1
Illustrator 2026 embeds duplicate instances of the same bitmap separately when saving a PDF, causing the PDF size to increase with every duplicate.
To test this, I used one 2000 × 2000 PNG file that is 7.5 MB. I placed it once, duplicated the placed object a total of 9 times, and saved the same layout as a PDF using comparable settings in Illustrator 2025, Illustrator 2026, and InDesign 2026.
Results:
Illustrator 2025 version 29.8, Adobe PDF Library 17: 8 MB
Illustrator 2026 version 30.3, Adobe PDF Library 18: 71 MB

Negative numbers go positive when posting data into the graph tool
Negative numbers go positive when posting data into the graph tool.
Since I remember I have had to type a minus manually to each negative cell into graph tool data, since it won’t paste the minus sign. This is extremely time consuming and often leads to errors in the graph. Is the a way to get around it that I have missed, or are you planning on fixing this issue sometime soon?2 votes -
Arabic text engine: keep letter shaping when converting to outlines
When Arabic text is converted to outlines in Illustrator, the letter shaping occasionally breaks on ligatures, and copy-pasting shaped text from InDesign into Illustrator still loses joining in some fonts. A more reliable Middle Eastern text engine, with a shaping check before outlining, would save a lot of manual rework for designers producing Arabic signage and transport guides.
Most of my Arabic layout work is for public information posters — timetables, tariffs and wayfinding.
A preflight warning when a glyph would lose its contextual form would be a small but valuable addition.
