Created attachment 87823 [details] screenshot of desktop settings I have set my desktop background to a slideshow, then select custom folders for images; add images and apply but when returning to add another folder, there are no entries in the custom folder list. Although, it appears my folders are being accessed for the background I also notices system wallpapers are being displayed when I haven't selected that option.
