Publisher macOS: images mixed with each other

[hawke]

On Publisher v2 for macOS, images on one spread of pages exported to PDF become mixed with each other: part of an image shows up on the next image. There are 12 spreads in the book but I only noticed this issue on this set of pages which also happens to have the most images. Happened on 3 out of 3 export attempts, although the glitch varied slightly each time in terms of the exact point at which the mixing starts on each image. At the points where they mix, there is also visible distortion, and it's not a straight horizontal line parallel with the x-axis.

 

So I tried exporting on Publisher v2 for Windows, and the issue didn't occur there. Same export settings (same as default for PDFs but disabled image downsample/compression (I use another app to create compressed versions), and enabled inclusion of links, bookmarks and invisible layers).

 

I attached screenshots of exports on both devices for reference.

 

I'm using the latest versions of Affinity Publisher v2, macOS and Windows at the time of writing. The Mac device is a MacBook Air 13-inch M3 2024, 16 GB RAM, 512 GB storage with sufficient storage left.

 

Any ideas on resolving this issue for macOS?

Welcome to the forums @hawke apologies for the delayed response,

I'd suggest disabling Hardware Acceleration (H/A) found under the app Settings -> Performance. Once the setting has been unchecked close the interface and restart the app when prompted to before trying the export again. There's a known bug logged internally with raster corruptions occurring with H/A enabled on PDF export on Apple Silicon based Macs and can typically trigger with JPEG Compression & H/A enabled.
