100% scaling is anything but
I have a MacBook Pro 16" (Intel) with an external Samsung 5k monitor.
Starting recently, when I select View –> Actual size I get a tiny document not by any means represented @ 100%. See screenshot.
Formerly, the command has rendered an almost 1:1 representation, which is what could be expected (not least since the command is called "actual size" and that the resulting window header says "100%").
The issue is described here: https://community.adobe.com/t5/indesign-discussions/recent-changes-to-gui-scaling/m-p/12578562.
