Hi!
I wanted to keep sprite fullscreen by manipulating its scale. Well, it was working only on original window size. If window size is lower than original window size, then sprite size is lower than window size. If window size is greater than original, then sprite is greater than window. It looks like this

Here's my code:

I'm using newest SFML, right from repo.
