I had the same problem, and I solved it. you have to use the Key Item "Anime and map Portraits" and turn second option off. then, you can use the "Hide Screen" item, and it will work properly.View attachment 2326879
Idk how but my game have the portrait of serena stuck to the screen. This portrait overlay this part of the screen and just keep staying there. I tried everything, including using the hide screen key item but none of them works. Does anyone know how to fix this?
