my retina display has shadows from previously opened programs
The retina display on my 13" Macbook Pro is stained from a previous opened program. I frequently work with MO Word and I recently realised it has a shadow on my display. It's a perfect match with the Word's layout, as it has "printed" its image on the screen. It's really light but undoubtedly there. How to reset or restore it?? Please help!!
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
