The lines on the screen you get when you press down too hard?

[Dooper]

Hey, I just noticed this last night, something new..


You know those scriggly lines you get on your screen if you press down too hard? You know those weird lookin lines that look like waves..

Well, I never press down hard but today I noticed that there was some that just didnt go away on the screen, and when I move my finger on my screen the lines move with it and stay in one spot.. Dont think water got in it, it's annoying though. Does this eventually go away?
