Okay, let's see if I can explain. I'm pretty new to this. The thing is, I created my first wallpaper and everything was fine, but then I uninstalled the app and reinstalled it a few days later. Now, everything works as it should, except when the app is running in the background. I mean, while I'm viewing the wallpaper directly, everything's fine, but when I open the app drawer or go to the recent apps tab, this red smudge appears. I don't know how to get rid of it, and I don't understand how it got there since the first time I used the app, it worked perfectly. I don't know if it's a bug, but I'd appreciate any help, or if there's something I'm missing. I have a Motorola edge 60 fusión btw
