Wagger, it's not a matter of it developing the problem, it's a matter of you just not noticing it yet!
I've already been cussed out (jokingly) by people who claim that the problem doesn't exist, but realized that it does in fact exist when they dug into it a bit. It's one of those things that once you notice it, it will drive you bonkers! You know, like seeing a disturbing image.. you can't un-see it!
Anyway, for that reason I would recommend you not pay any attention to all of this!
