AI 25.4.1 / Win10

ACTION TAKEN:
Saving a copy of A2 sized AI project as PDF file (print-production style).

RESULT:
Extremely huge printer marks in PDF (see screenshots)!
Tried several PDF versions in saving dialogue with same failed result.

WORK-AROUND:
1. Verify artboard size (and PDF document size as well) several times, just to be sure if my mind works OK this morning. And it's working fine (sight of relief, :-)
2. To make printer-ready PDF, original AI file was imported to InDesign (via import, cmd+D).
3. Then, upscaled imported graphics to 100% (which made me guess than original AI is somehow saved in 1:10 scale).

Resizing a text frame using Resize tool or scripting API fails to resize the text within that frame if the resulting text would be greater than 1296 pt. This bug affects both the manual Resize tool and the scripting APIs (both resize method and size property).

To reproduce, create a text frame containing text at 129.6pt. Select it, then double-click the Resize tool and enter 1000%. This works correctly. Undo, then repeat for 1001%; this time the frame resizes but the text does not.

Using the equivalent JSX, the following fails to resize the text:

app.activeDocument.textFrames[0].resize(1001, 1001)

Setting the text size directly also fails:

app.activeDocument.textFrames.getByName('script 2').characters[0].size = 1297

Error 8753: invalid text range

Objects copied to clipboard do not have the same SVG formatting as previous versions of Illustrator when pasted as text to other programs.

Illustrator has a feature that lets you copy objects to your clipboard and paste them to other programs as SVG code. This is found under Preferences > Clipboard Handling > Include SVG Code.

2021 (25.4.1) isn't handling the SVG code as 2020 (24.3) and previous versions did. Instead of neatly formatted SVG code, you get an unformatted mess that is... just a mess. I don't know if this is even XML.

Is there some obscure setting that changed defaults from 2021 to 2020? Using the Save As dialogue produces the correct results, but I need to be able to copy and paste if at all possible.

I've attached some files to help demonstrate what my issue is and show the results I'm getting. There are just random objects and groups tossed in there to give it some formatting.

I'm on Windows 10 running AI 25.4.1. It works just fine in 24.3

When I open some of my ai files the text inside a text box disappears. If I try to create a new text box to replace that text it keeps disappearing. This only happened to me after updating to Big Sur. It's extremely frustrating as I haven't found a way to work around it.

First photo is how it appears when I look at a preview of the ai file before opening, second photo is what it looks like when I open the file. (Don't mind the black lines, I wanted to keep that info private)

When creating shapes with the pathfinder or shapebuilder, there is a problem with rendering where curved and straight shapes intersect. I have tried multiple files, updated Illustrator, and even opened old files to discover that the rendering issue is there on files that were made ages ago without issue... so the problem is not with the tools, but with how these shapes are rendering. It's totally frustrating because precision work is impossible at the moment!

I do use snap to grid, but have tried with and without it. I have ensured that snap to pixel is off, as this causes other issues.

For this example I've intersected a circle and square to create sharp corners. The results are consistently problematic.

I've added screenshots of
1. the overlapping shapes
2. I used the pathfinder to divide.
3. I show the problematic rendering up close
4. I show that there is no abnormality in the wireframe view.

To further test the issue, I made a couple of copies and rotated them. The screenshots here show

1. that the rendering issue changes depending upon rotation and
2. again there are no issues in the wireframe view

I understand this may not be as common a use-case, but while trying to figure something out, I was puzzled when undo did not return to the state I was expecting. Below are the steps to reproduce this issue:

Create a shape, such as a rectangle. Give it a color.
Create a different shape and place it somewhere overlapping the first shape. Give it a different color.
Select both shapes and create a Clipping Mask by right-clicking and selecting "Make Clipping Mask"
You should now see only the overlapping parts of both shapes, as expected.
Open the Pathfinder panel and click on the menu icon and choose "Make Compound Shape".
The outlines of both shapes should be visible.
Undo, and the overlapped clipped shape step is skipped and instead, only the first shape is colored and the selection is a group, which was never made.
Undo again and the second shape is colored.

I'm not sure what the expected result should be. Maybe as if they were never clipped at all? To be honest, I was looking for something like the Merge function, without creating empty fill shapes. This doesn't do anything like that though.
It looks like instead of making a Clipping Mask on redo, it's just grouping? I've provided a video.

My system is Windows 10, 20H2, 19042.1165.
Illustrator version is 25.4.1

When I add an item to the Asset Export panel and then export it, the exported graphic is including a lot of extra pixels that weren't part of the item/group that I added.

In the attached screenshots, I first added an item. Then, when I deselected my item, the panel added extra padding to the asset. Then, when I went to export my assets, there was extra padding on almost all of my assets. I opened them in Photoshop to crop them back down to size. All the files had some stray white pixels that are not in my AI file.

I've had this happen on multiple files, for a long time now.

When I transform an Area Type text box using the handles, it resizes the Area and the type fits according to paragraph settings - which is what I want from Area Type - (first part of video).

But if I transform at the same time as another shape, selecting both at the same time - the type resizes like point type, stretching and scaling with the box, which is not how area type should behave - (second part of video).

So I can't transform an Area Type text box at the same time, for instance, as a holding shape that I want to align it with - I have to do them seperately whihc is very sslow and inefficient.

As a graphic designer I literally NEVER want to stretch type in this manner, and If I did i would choose point type for this reason - (last part of video shows this box is indeed Area Type).

Thanks
