Clipping masks not working with images with opacity masks

Community Beginner ,
Sep 09, 2025 Sep 09, 2025

Hi guys,
Another bug in AI 2025 29.7.1 that wasn't in more stable versions like Illustrator 2020. Now, you can't place an image with an opacity mask within a clipping mask, without the outer corners of the clipping mask showing as white when placed on top of another object. It doesn't matter what shape the clipping mask is – it will turn it into a object with square corners with the excess being all white. Very annoying bug and very hard to work around when doing signage design etc., for client designs. You can see in the video, the image works fine within the clipping mask if there's no opacity mask on the image.
Please fix this ASAP!
Many thanks!

I cannot replicate it in 29.8.1, but I have seen examples of this that disappear when CPU Preview is used,

Can you check that: Cmd or Ctrl E to switch Preview.

Hi Ton, thanks for the message! I have just checked, and if I switch to CPU Preview, it corrects itself, but not on GPU. What does this mean? Should CPU Preview be used instead of GPU?

If your computer happens to have a graphics board with an NVidia chip set check to see if the graphics driver is up to date. BTW, NVidia released an update earlier today (version 581.29). Also, computers that have NVidia graphics boards tend to have the Game Ready driver installed by default. I think the Studio driver works better.

What Bobby said, check for driver updates. Working in CPU Preview is slower, but more precise. I would work in the faster GPU Preview and from time to time switch Preview with Cmd or Ctrl E to check.

Hi Ton, on a Mac, I can't update graphics card drivers as they are part of the OSX. I have done the same thing however on the same computer, same graphics card, on Illustrator 2020, and no issues even without the GPU Preview  – so this shows me Illustrator is causing the bug, not the graphics card. See video attached. To me this therefore appears to be a bug.

I see, then it would be good to mention it as a bug in UserVoice, where it can be tracked and seen by the Illustrator engineers.:
