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.

I haven't done a deep dive to see if it's sending data out, but it's something worth considering. 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. 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. The implementation probably needs some work or explanation. System Requirements: macOS 10.10 and higher, 8 MB. It's a lightweight app that does one thing keeps your drives clean but does it so well. Download it now to remove all the invisible junk your disks contain. The pro version works with multiple desktops, also works fine. CleanMyDrive 2 is ready to do the job on your drives. Does what it says with a caveat (Screen Recording prompt)
