Sprite disappearing after recreating window

[Gabriel_]

I'm really new to SFML.
After i recreate a window one of my sprites disappears.
It's the sprite that i use to make the fade effect and it has a completely black 1080x1080 texture

this is the code that i used to recreate the window:

mainWindow->create(sf::VideoMode(screenX, screenY), "Game", sf::Style::Fullscreen);
