What settings exactly do I need to adjust to get the background showing with black borders surrounding the tiles? I can get it with solid color tiles, but not with a wallpaper image.
Thanks!
Edit: After poking around more I finally found it.
Launcher Preferences > Themes & Colors > Dark Theme Options (or Light Theme Options) > Background
Choose: Tile picture (experimental)
I had kept trying different slider/transparency options and wasn't having any luck there. Nice that it is an option, just really buried. I think this option might be better in the Wallpaper options as that is where I had looked initially. Hope this helps someone!
