How to fix some objects disappearing behind white masks?

Question

This is hard to explain, but in short: sometimes artwork disappears behind an unseen white mask that I cannot get rid of. And sometimes it does not. All my artwork appears correct however. The only way around it is to CTRL-X and CTRL-V. While this works to an extent, it removes any and all effects if an object had anything. Below is an example: The grey box is stretched outward, but due to this white mask, you cannot see it. And it has an effect on it that is removed from the aforementioned method.

Adobe Acrobat Pro 32-bit.

Any help would be appreciated.

Hello,

I hope you're doing well, and we apologize for the delayed response and the trouble.

Is this issue occurring with a specific artwork PDF or all PDFs? Did you create the PDF yourself, or was it generated using another application?

Please ensure you have the latest version of Acrobat installed on the machine: 24.005.2039x Planned update, Jan 23, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check.
For more information, see this: https://adobe.ly/4hy0DvS.

Also, try resetting the app preferences once, and then reboot the app and machine. To reset preferences, please see this article: https://adobe.ly/4hfhfZG

Let us know how it goes.

Thanks,

Anand Sri.
