I have Windows 11, up to date as of 12/21/2025, and displayfusion v12.0.1 (updated today). Unfortunately, the wallpaper setup I use doesn't seem to be working any more. I have three monitors, APOD slideshow on one, a slideshow of wallpapers from a local directory on my computer on the main monitor, and google earth images slideshow on the third. Unfortunately, while the scaling setting seems to be changing when changed in displayfusion, the wallpaper images do not seem to be being set properly or put into the right locations. All three screens only display the single image defined in the Windows background configuration now. It was working properly yesterday, so I strongly suspect the v12.0.1 update.

Since this is the first time I've had an issue with DisplayFusion, I'm not sure of the debugging process, but I've attached a DisplayFusionDebugInfo zip file.
