Flickering of pixels on screen?

[unlimitedx]

I noticed that on my iPhone 5, occasionally there is a line of pixels that flickers a white line. Anyone experience it or know what is going on? I don't know how to trigger it

Edit:
This is the issue I have

Yeah, I've seen it on mine a couple times. The last time I remember it, it was when I was using my keyboard

I get it when I'm typing my password for iTunes after trying to install an app, it is very repeatable

this started happening to me too -it only happened once, but it was when i was using the keyboard to put in my password for the app store.

Same thing here. Noticed it in the same instance too, when the Keyboard pops up for iTunes password in AppStore...looks like a line or 2 of pixels.
