I have a 2017 macbook pro 13 inch. I'm noticing that sometimes the screen becomes pixelated similar to symptoms of a failing graphic card but it would only present itself for a second or so, typically playing something on youtube. Also, my keyboard randomly starts having the spacebar depressed. The problem goes away on its on and returns occasionally. I'm thinking about taking it to an apple store but would it be better to live chat or call apple instead? Usually, geniuses won't do anything unless you can replicate the issue at the spot.
