I think the developer needs to respond to this and listen to the Accidental Tech Podcast episode 356 starting at 1:32:17, John Siracusa describes this exact problem. I'm willing to give the developer the benefit of the doubt, but this is conjecture because as a non-developer, this is how I would do this. So, I assume the developer is using screen recording to grab the current desktop backgorund and then display that image on top of everything, hiding your icons. Magnet in AirPods and MacBook provide convenient place to hold your. I haven't done a deep dive to see if it's sending data out, but it's something worth considering. Lifehacks: Uncommon solutions to common problems. It's a messy implementation and the easy way out and without proper notification, causes freak outs and 1-star reviews. One of the options was to use Quartz Display Services which can grab an image of your desktop background, but it requires screen recording to do so. Installing an application distributes many files throughout your System using space of your Hard Drive unnecessarily. I'm not a developer, but I'm reminded of John Siracusa talking about his app SwitchGlass (which is awesome btw), and the implementation of grabbing the desktop background for use in the app Preferences window. AppCleaner is a small application which allows you to thoroughly uninstall unwanted apps. The implementation probably needs some work or explanation. The pro version works with multiple desktops, also works fine.
Does what it says with a caveat (Screen Recording prompt)
