I'm using a 2019 Mac Pro with all the latest Adobe software. When Acrobat is open and in front of the Finder windows and other apps everything is fine but when I click into another app or Finder window, while Acrobat is open in the background, the Acrobat cursor remains visible. Hiding or quitting Acrobat is the only way to restore the correct cursor. When this occurs while working with another Adobe app (e.g. Illustrator, Photoshop, InDesign) the cursor flickers between the Acrobat cursor and the other program's cursor. There is a flickering cursor bug which has affected Adobe software for many years which has never been fixed. This may be related to that bug.
