Black Screen after unlock

After i unlock my LG G5 it takes about 3-5 seconds to load the wallpaper. Im running Android 7.0 with Nova as my launcher. Is there a way to get around the long loading times on the wallpaper?

If that happens it means that something is wiping KLWP from memory, this is nothing i can fix, please ensure there are no tools like Purify or Greenify that might remove the process
