The linked pdf file was created in latex, and displays correctly (with the dark blue blackboard

background) in Acrobat. However, the background disappears in Reader.

AI does not help.
How can one solve the situation?

Note also that if I try to download the Reader from Adobe, it downloads an older version (ending with 12771) than the one I have installed. So there is a second issue here as well.

Hi brilliant_friende0a0,

Thank you for the information.

Please try manually updating the application. To do this, go to Menu > Help > Check for updates within the application. Alternatively, you can install the latest update from the following page: 26.001.21789 Out of cycle update, Aug 11, 2026.

Could you please share a screenshot of how it appears in Acrobat and Reader? Additionally, please check if this issue occurs with this specific file or with others as well.

Thanks,

Meenakshi

I already have that update installed.

Here is a screenshot of the correct file, as displayed by Acrobat Pro, with a blue background:

Here is how it appears on the Reader, with a white background:

This is a situation that happens for all my files with this dark blue background.

But with all of them. (I have several versions, and it happens with all of them.)
There is no problem with other files.

It is a public file, so do not worry about privacy.

You will find several similar dark blue files for free download at

that you can use to test.

Best of luck to the team in finding the bug!

OSX, Desktop, very latest OSX (thus also happens on Tahoe 26.6.2),

and very latest Reader.

Hi brilliant_friende0a0,

Thank you for reaching out, and sorry for the trouble caused.

As mentioned, the PDF background appears in Acrobat but disappears in the Reader. Could you please confirm whether you are using the mobile version of Reader or the desktop application? Additionally, please provide the version details for the Reader and the operating system on your device.

We will review the file and provide you with the correct information.

Feel free to let us know if you have any questions or need help.

Thanks,

Meenakshi

Just for completeness, the file displays correctly, with the dark blue background, on Safari on my iphone (also latest iOS).
