Hello, i'm trying to make medals appear in a Flappy Bird game but when i do se the medals pops with a very bad resolution and i don't know what to do ? It surely has something to do with the fact that i use virtual resolution ( push:setupScreen(VIRTUAL_WIDTH, VIRTUAL_HEIGHT, WINDOW_WIDTH, WINDOW_HEIGHT, {
vsync = true,
fullscreen = false,
resizable = true
})
)

but don't have a clue about how to resolve this.

Any ideas guys ?
thank you !

Hello, could you attach a .love file and/or explain what's wrong with your game specifically?
