I can reproduce this problem briefly in 18.04 (where the memory usage jumps dramatically), but after changing wallpapers 3-5 times the memory usage stops growing, or jumps back down to its original size. So I think there's probably still something to fix here in 18.04. But also, changing wallpapers is not something most users do very often.
