After images? (for lack of a better term to use)

Anyone else experiencing this red after image thingy on the sides of the screen? It is most noticable when looking at a dark image or completely black. See image below and notice the sides.

I mentioned after images because the icons on the status bar sometimes shows an "after image" when for example I toggle the wifi off thereby the wifi icon disappearing, an after image is left behind but not that noticeable.
Any thoughts as to what it is and possible remedy?
