I'm on Windows 10 pro, version 21H1. The version of illustrator I have is 26.3.1.
When working on a document, CMYK or RGB, in illustrator with my Adobe color settings synced across all programs, all PNGs whether 16 bit or 8 bit turn negative. I've attached before and after screenshots.

I've never had this happen before and I work with PNGs everyday, I spoke to and adobe support rep yesterday and gave them an AI filer where I tested PNGs vs JPEGs out. JPEGs are totally fine, only issue is with placing PNGs and I rather place a PNG than put in a huge transparent photoshop image.

It happens to all PNGs, even the ones I've made via exporting a vector image as a PNG.

After suffering through terrible support through the chat in Adobe Admin Console (basically just telling me that I'm wrong), I've been redirected here.

Here's the bug:

In Illustrator 24.1.X, all links will be broken when you try to open a recovered document. This does not happen in 24.0.X

How to reproduce:

Create an AI File

Link a png from the 'Links' folder next to it

Save it

Make an edit and let it Auto Save

Force Close AI

Open the 'recovered' file when it asks me

You are met with this:

'Could not find a plug-in to read the linked file "Links". Choose Replace to select another file or ignore to leave the link unchanged.' (screenshot attached)

The message repeats for however many links you had.

If I ignore it, you're met with links that have no name, no format, and no location. The ONLY identifying information is the resolution.

These tests were carried out on a Mac running 10.15.4.

This is an egregious bug.

The support agent I spoke to confirmed that this happened on Windows too, but proceeded to tell me that this was 'expected' behaviour, which is nonsense.

When moving/rotating/scaling Raster images should always honor the layer order and transparency values.

With "show images in outline mode" selected, I often drop in low res raster images on the bottom layer and outline them with the pen tool in higher level layers.. problem is the way illustrator handles raster images. If i draw a line on top of a raster image, then attempt to scale that raster image, my line is temporarily hidden while scaling, moving or rotating the raster image, making it nearly impossible to re-align my raster image to match newly drawn vector lines. Also, raster images with transparency are temporarily opaque when moving/scaling/rotating. so any foreground lines i may want to use for a scale reference are invisible when using the move/rotate/scale operations.

If you open a multi page PDF in Illustrator and then copy and paste it either into the same document or a different one, it changes from cropping to the bounding box to whatever was specified last in the File/Place options dialogue box and scales up or down to fit the same space.

If I place a file (any file) and specify cropping to Bounding Box, and then open the same multi page PDF as before, the problem does not occur. It appears that by opening a multi page PDF it crops to bounding box but by copying and pasting it reverts to the last used cropping in File/Place and resizes to fit.

This issue is present in both Illustrator 2021 and 2022 on Mac OS 10.15.7.

When you Image Trace, using the default black and white tracing preset and expand - the black and white are grayscale. When you double click the fill in the toolbar to choose a new color for the black or white, the resulting color is a shade of gray. Then, you have to go to the Color panel and change the sliders to a different color model to be able to see the color you chose. It would be easier if the black and white were aligned with the document color mode, RGB or CMYK instead. You don't encounter this issue if you apply color from a saved swatch, only when using the color picker.

When exporting an AI file with an embedded PNG screenshot (added via File > Place) as an SVG, the <image> tag in the exported SVG file is no longer being created with "width" and "height" attributes.

This creates an error when trying to use the exported SVG in XMLmind (which states that there is no width attribute on the <image> tag), and I imagine in other contexts as well.

We're on an enterprise cloud subscription of Illustrator, so at any given time we're working with the most up-to-date version. In a similar file I exported to SVG back in January 2021, it worked just fine. If I had to guess, the issue popped up at some point in the past 6 months. I've attached screenshots of the export options I've used for a few years now, as well as a sample of the exported SVG output from back in January 2021 (the top code sample) and just the other day (the bottom code sample).

Similar to https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/44963893-svg-code-export-issues, downgrading to version 26.0.3 once again exports these same SVGs with the width/height attributes included in the embedded <image> tags.

When I drag and drop a JPG/PNG/PDF/AI file from Finder into an Illustrator document, it normally drops in as a link. However, sometimes it unexpectedly embeds the artwork instead of linking it. If I try again repeatedly, it continues to embed, so to fix it I have to go to File > Place and ensure that "Link" is selected (which it already is). After that, if I drag-and-drop from Finder again, it links the artwork as expected.

This issue is seemingly random and I can't figure out exactly how to reproduce it. I always link files (not embed them) when I place them via File > Place or via drag-and-drop, so I don't know why it sometimes decides to embed.
