I have a Late 2015 27" iMac with Retina screen, as well as an external (non-Retina) monitor (1680x1050).
When moving Acrobat's application window from the external monitor to the iMac's Retina screen, most of the displayed page fails to automatically redraw... only the top left of the page displays. Zooming or otherwise changing the view percentage brings it all back. Current version 2022.001.20112, but it has been happening for previous versions as well.
