Screen of MacBook Air is glitching at the bottom and spreading up
My MacBook Air is glitching at the bottom of the screen with colorful horizontal lines / grey boxes/mirroring effect. It started small but has continued to spread upwards. Does anyone know the cause or a fix for this? (photo is the bottom half of my screen and the warping starts just below where the cursor is.)
MacBook Pro 13", OS X 10.11
