For the past few days I've had a bunch of thin black lines on the left side of my screen (mid-2015 Macbook Pro), and my screen is shifted so that I can't access the Apple Menu on the left. When I move my Dock to the left, it also disappears. I've tried resetting the PRAM and changing the screen resolution, but this hasn't helped.
I have an extended warranty, so can bring it in for a fix, but if there's a simple fix of course I'd rather do it on my own. Any ideas what's going on?
(Interestingly, when I tried to take a screen shot to post here, the lines weren't visible to the internal camera, and I could see the Apple Menu on the far left of the screen shot although it's not visible on my actual screen. The photo looked exactly as the screen should, but the screen itself is definitely wonky.)
