Border width problem with iiif-viewer


I’m having a problem with the iiif-viewer integrated into Omeka: the rectangles in my annotations are very thick (see image : Capture d’écran 2024-06-27 à 12.59.50.png) and I can’t find what to do to make them 1 pixel thick.
I don’t have this problem with the Mirador module developed by Daniel Berthereau
My version of omeka-s : version 4.1.0

Thank you in advance for your help.


What’s the manifest you’re using. That’ll help us troubleshoot the issue.


Thanks for the feedback. In fact, this happens with my manifests ( ) and those of other institutions (

Best regards

We believe it’s a bug in Mirador. We’ve submitted an issue on their repository and hope to get an answer soon.
