I have come across 2 problems.

1- Whenever i touch the home button twice to switch between apps, the default launcher comes instead of lightning. It also happens if i come to the home screen from closing the foreground app. I’ve set lightning launcher as the default and still this happens.

2- When i set individual wallpaper for my main desktop, the image does not fill the whole screen. It comes as a tiny box centered in middle on top of the system wallpaper. I tried the stretch to fit option but it destroys the aspect ratio. I tried using wallpapers of more than 1920*1080 and still get the wallpaper as a tiny box.

Edit: How to remove the wallpaper for an individual desktop? I had to go back to a previous version of my desktop which i had saved to remove the individual backgrounds and only use one system wide wallpaper.

Also is zooper pro really required for using lightning launcher?
