Default Slower refresh after wallpaper change

Hello, in the past, the weather and S Note windows (the top two windows on the home screen that show up after the home button is pressed) show up instantly. However, after I used an app called Galaxy S5 Wallpapers to change the wallpaper of my Note PRO 12.2 LTE, sometimes there is a pause of about a second or two when the home screen is reached. Changing the background back to those in SecWallpaper Chooser resolve the issue but the issue shows up again after I changed the wallpaper back to that of the S5 using the Galaxy S5 Wallpapers app. Do you know what is going on?
