NOTE: tested several times:

  1. Get the same issue on diagrams that have image background
  2. The diagrams that don't have backgrounds are working fine

I could reproduce with the imported diagram, but it is repaired after a new Save of the page. It was the same even before editing it?

Get the same issue on diagrams that have image background

Meaning that you reproduce the same for new created diagrams with background? Or for other diagrams created in a previous version of Diagram Application? For me I couldn't reproduce for new diagrams with background, neither for diagrams that were created in Diagram Application 12.3 (previous version) and tested after upgrade.

The issue with the diagram appeared when you opened the diagram after upgrade? Or you performed any additional steps before observing the broken Attachments Tab or the errors? The background image was added using 'Actual size', or with 'Resize' option?

@oanalavinia The 2 Diagrams that had issues were created with prior version of Diagram. I've edited and saved them but nothing changed.

I've created a new Diagram with background image and it is being saved properly.

I saw the broken png after I changed in Object mode from SVG=Yes to No and made changes to the zoom option - I've tried all options from 1 to 5.

The Images were added from the right panel - one with an image from my computer and one with a link to a image. The sizes were the default.
