Hi @jackbrannen_pl,
Thanks for sharing the details. Could you confirm if this issue is limited to this specific document or if you're seeing the same behavior in other files as well? Also, is GPU Performance currently enabled under Preferences? If it is, please try toggling it off and let me know if that makes any difference after restarting InDesign.
It would also be helpful to know if this behavior only started after updating to macOS 15.6, or if you were experiencing it on earlier versions too.
If possible, a short screen recording showing what the text looks like before and after zooming or panning would be great to help us look into this further.
Looking forward to your update.
Abhishek
