Memory leak....Maybe?

I can't seem to figure out if my program has a memory leak or not. I've run various tools to look at it and I still don't know.

I'v run Valgrind on it and it reports a few kb of lost memory, but it doesn't seem to be from my code:

Also, when I look at my system monitor(KDE system monitor), it claims that my program is using a horrendous amount of memory(several hundred GB).

I'v also manually stepped through my program with a debugger and did not notice anything.

Accord to a Valgrind's Massif tool, it says my peak heap size is around 60mb.

BTW, why does SFML use so much memory?
