Letters showing on different parts of screen...Password entry in app store

Just today I was downloading an app on my phone, the normal password pop up appeared and I am entering mine in. I get to certain letters/numbers and they not only appear in the password field but when I type them a little flash (in different areas for different letters) comes up momentarily. It almost looks like an "accesability" type option but I do not have any of those functions enabled.

ANyone ever heard of this and how do I correct it?
