This often happens when I quit apps in fullscren split view mode? Has anyone encountered this too? Any known fix for this?

  • If it started happening without any new app installation, and only after a update, better file a bug at feedbackassistant.apple.com/welcome – anki Feb 23 '20 at 8:29
  • Yes. I've had this happen in 10.15.7. I'm surprised that no one has answered. Perhaps a rare bug indeed. – Jeffrey J Weimer Dec 28 '20 at 23:20
