flickering on screen
Ok here's what my desktop looks like. I actually couldn't do a screenshot so I recreated what it looks like in photoshop. On the right side, it's not smooth, it's separated and flickering. What can I do?
I've got a MacBook pro late 2012 retina.
macOS sierra 10.12.2
Intel HD Graphics 4000 1536 MB
2.5 GHz Intel Core i5
