When saving an existing ai document that I have made an alt to illustrator keeps giving me a save error.

Illustrator tried, but could not save the file 'file name' Click "Learn more" to try alternate options for saving a file.

If I then use the 'save as' command and save over the top of the existing ai it will save. Illustrator leaves a .tmp file in the same folder as my ai. I may work on the file a few more time re-saving using the 'save' command with no issue and then randomly I will save and we go through the same issue all over again.

This happens multiple time throughout the day on any ai file I'm working on.

.tmp files just keep piling up until I delete them.

Could this be a compatibility issue if I am still using MacOS Mojave 10.14.6 and Adobe Illustrator 2020 [24.0.1]

I have pasted art from AICC2018 as smart object inside PS.
I have saved and closed this art in AI (just in case).

Now I double-click smart object inside PS and it AI opens embedded art (not that saved separate file, of course). I select envelope in this embedded art, try to release it and AI crashes.

If I try to open separate saved copy and try to release envelope — it works fine.
If I copy and paste art from embedded file into new file and then try to release envelope —it still works fine.
Please try this yourself with file attached and see animation recorded.

I run English AI CC2018 in Russian Windows7x64.
I also have flags unchecked in Prefs to make Y-axis go up from bottom left.

As of last week, I have been encountering an issue with file sizes growing larger and larger each time I save. The file grows even when I only move or even delete objects. The larger the file becomes the more it adds with each save, and the slower it becomes. It’s as though it’s doing something like saving history states (although not in any useful way).

This is a huge problem; the project file I’m currently working on, though modest in complexity (75k points, only a few effects going on) compared to other files I work on, has grown to over 130MB when I’d expect it to be around 20MB. Each time save the file, even to remove parts of the picture, it adds MBs to the file size. It’s currently taking 30 seconds to save. It has ceased to be usable.

Things I’ve tested in an attempt to resolve the issue:
• Uninstalling plugins
• Reinstalling illustrator
• Testing files on 3 other PCs around the office (they all have the same issue)
• Deleting all objects with effects of all sorts
• Expanding artwork
• Deleting symbols, graphic styles, swatches etc
• Vector First Aid, removing points, unnecessary groups, masks etc. (before I tried uninstalling plugins obviously)
• changing colour mode
• 300dpi > 72dpi raster effects

None of that helped.

I also tried making a small file and adding text and paths, then saving and moving objects and re-saving; the file starts small but grows with each save. The larger the file size becomes, the more the file size grows, regardless of the artwork complexity.

The ONLY thing reduces the file size back to normal is saving in CS6 format.

I do have issues with Illustrator displaying transparencies of placed PDFs as solid.

Steps to reproduce:

1. Open a new document.
2. Draw two partially overlapping rectangles with different colors.
3. Set he opacity of the frontmost rectangle to 50%.
4. Save this document as a PDF with setting Illustrator Standard (see attached file).
5. Open a second document.
6. Place the PDF file.

Expected result:

The topmost rectangle should be displayed with transparency.

Actual result:

The topmost rectangle is not transparent.

If you save the document with the placed PDF itself as PDF file, the rectangle is still transparent, so this is a display issue of Illustrator. Now it’s getting really weird: If you place this second PDF file in a new Illustrator document … all looks fine.

I am using Illustrator 25.0.1 on MacOS 10.14.6.

When I export a JPG from the "Export for Screens" dialog at any resolution (I usually do 300dpi), placed raster graphics have a jagged edge. The same artboard exported at the same resolution with the same anti-aliasing settings using File > Export > Export As turns out nice and smooth.

Note: neither "Type Optimized" or "Art Optimized" settings help. Resetting AI preferences did not help.

Operating System: macOS Mojave and Catalina (happening on two different systems)

Steps to Reproduce:
1. Create an artboard in Illustrator
2. Place a raster image with curved edges such as an oval, especially if it's rotated slightly
3. Export the artboard as a JPG at 300dpi using "Export for Screens"

Expected Result:
Nice smooth JPG that looks like my artboard, like "Export for Screens" used to produce.

Actual Result:
JPG with jagged edges on placed raster images.

A .zip file is attached with original AI file, placed PSD graphic, and two exported JPGs. JPG 01 was exported with "Export for Screens" and JPG 02 was exported with File > Export > Export As.

Operating System: macOS Monterey v12.1
Illustrator version: 26.1

Steps:
1. Open .ai file or .svg file in Illustrator that uses a gradient
2. Export as SVG with the following settings (see attached screenshot):
- Styling: Presentation attributes
- Font: SVG
- Images: Preserve
- Object IDs: Unique
- Decimal 2
- Minify: yes
- Responsive: yes

Expected Result:
- The SVG elements use the "fill", "stroke", etc attributes directly
- No <style> tag
- No inline style attributes in the SVG elements
- Object IDs are random strings (uuid)
- SVG shouldn't have the <?xml starting tag

Actual Result:
- Object IDs are not random, it' using "a, b, c, d, ..." as the IDs - similar pattern to what Object IDs = Minimal would look like
- There is no styling applied at all
- When opening the file in Chrome, the styling is lost and most elements appear black

This is an issue because it conflicts with other elements on the web page that the SVG will be displayed on
