Yes, resaving the placed PNG as 8-bit with an sRGB color profile will solve the issue even on PC.

This issue is the placed image. If the PNG was (for example) a screenshot from an iOS device, it's a 16-bit image with Display P3 colorspace.

It's still crazy that Adobe re-introduced a bug that has already been solved.

Hello, Jens! Sadly this is happening to me on a desktop PC. Not sure if your solution will fix it if it's Apple-specific. I can try though might be less bother to just jump back to an earlier Illustrator version. Maybe.

For anyone still having this issue, or getting it again.
Try resaving your png file as 8bit with simple sRGB colorspace.
The original problem was with png files in 16-bit and the apple Display P3 color profile. Aka screenshots from an iOS device.

Can confirm the latest update has brought back this bug. Checked out an old file and all my pngs are trashed in the same way as the screenshot in the original post above shows.

no, its not solved. I have illustrator 26.3.1 and the problem persist. Everytime I open my file, I have to replace my pngs. It's ironic because adobe have so many problems and we pay for this s***!

i get same problem too, how to i fix it?

Still nothing better.....

When will this issue get fixed :( I did not have this problem before.

Yes, the problem is still there. Honestly, nothing seems to work!
It is really annoying & I hope they fix this soon.

Anyway, I'll leave here the link that will help y'all.
It really shows you the easiest way to fix that imported image super quickly. ;)

Have a good one everyone, stay safe! <3

Here is more documentation on the issue.

I can confirm the issue is still there, and that its isolated to MacOS.

The issue is with the Display P3 color profile and 16bit color depth.

for me it was because image was a 16bit. works fine as 8 bit on crummy 10.15.3

Same issue here imports just fine for illustrator on windows but if you do it on the mac version it looks like the above images. Old static tv look.

This is a 16-bit png. Opens fine in photoshop, opens fine on windows illustrator, opens as shown in attached with mac illustrator.

Also 6 months + for an issue like this is sloppy Adobe.

I thought this was a 16bit issue. Then I thought it was the Display P3 color profile. Whatever it is, it is fixed with a re-export of the the screen shot in PS. You can even skip converting the color profile AND leave it 16b it and the result displays correctly in AI. Not sure what about the iOS screenshots is the issue in AI but the work around is simple enough.

Same issue Iphone 8 plus. Any better idea then taking another screenshot of the screenshot once on computer?

I have the same problem - really annoying!

i have the same problem with Iphone 8+

MacBook Pro 13" Early 2011, 2.3 GHz Intel Core i5, 16 GB RAM, 750 GB HD
macOS (High Sierra) v. 10.13.6

Creative Cloud Subscription
Adobe Illustrator CC v. 22.1
Adobe Photoshop CC 19.1.5

Problem: Every time I import a .png file from Photoshop into Illustrator, I always have this bizarre problem. I usually go to File>Place and import the file as usual.

The problem seems to be solved by converting it into a .tiff via photoshop. I'm just curious on what's causing it.

Click on it once in finder, press space bar.

CMD + Shift + 4 then draw around it, open that in Illustrator.

They are both .png and should be the same size.

I have the same problem. iphone X screeshots won't open or open as jagged lines in Illustrator but open in Photoshop fine.

Screenshots by iPhone X (iOS 11.2.6) PNG files
Some problem happen on Macboop Pro (13" / 2101mid / MacOS 10.13.3 ) in illustrator (22.0.1)
But correct in Photoshop (19.0)

How can I fix this problem ? Thank you !!
