New clipping mask issue - phantom white box appears on display!

[susannahl23429837]

Hi all - I make clipping masks all the time, but today I had a wierd thing happen. When I clip a vector into a mask, I get a phantom white box. The box does not appear in the command Y preview and so far, it doesnt appear in my exported PDFs or PNGs. But it does make it hard to work because the image doesn't look right and blocks out the background. And ofc I'm concerned that the final print will have this issue. See the screenshots that I'm posting and let me know if any of you have seen this too.

Hello @susannahl23429837,

I'm sorry to hear about your experience. Could you share more details, like the version of the OS/Illustrator installed, system info (CPU/GPU/Memory) and if Illustrator behaves this way with all files, so I can better assist you?

Looking forward to hearing from you.

Thank you Ajlouny.  I have an iMac, Retina 5k, 27 in 2017 (getting a new Mac Studio soon!). 4.2 Ghz Quad, Radeon Pro 575 4GB graphics card.

I've never seen this issue prior to today -- and I make clipping paths all the time. It does sound like that other person's issue is similar.  Also, in the CPU view it is fine (I never knew about CPU view). The problem is in GPU view. And in Outline view the shape is not present.

We’re on the same system (the other person is me 🙂). The reason you don’t see the shape in Outline Preview is because this is a rendering glitch—there’s actually no shape there. What you’re seeing is the artboard color showing through the green object beneath the clipping mask. That’s also why the issue doesn’t appear in the exported PDF.

This white glitch seems directly tied to the area of the transparent content within the clipping mask.

If accurate rendering of clipping masks is critical to your workflow and you can’t work in CPU Preview, I recommend rolling back to version 29.5, where the issue does not occur.

Thanks so much! Mostly I just wanted to confirm that it's not going to be there on the print. I'll be updating my computer soon (hope you do too!), so I'm not going to worry about it. But I wasted alot of time this morning trying to fix the problem!

And, yes I am using Illustrator 29.6. Updated Friday, so I'm realizing now that this is the first day I've used it since the update.

Hi Susannah,

Looks like the same issue discussed here: GPU Preview glitch with clipping masks and transparency

If you think it is, please upvote the bug report here: [Bug Report] GPU Preview glitch with clipping masks and transparency (since Illustrator 29.6.0)

I rolled back to Illustrator 29.5 until the issue is resolved.
