Tried on Windows myself, the game indeed leeks ~500KB every time the main menu music sequence ends. This is much less frequent than on Wine because the music segment actually plays for a couple of minutes and reloads less frequently.
OK, thanks for the explanation and especially for the effort you made fixing this bug.
