I have found 3 ways to reproduce graphic glitches on the new macbook pro 2016. Even on a clean install with latest .2 version of sierra. 1. Start siri so the siri window open. Then toggle "automatic graphics switching" in the energy saver preferences. This produce a yellow colored glithc in the siri window. (most likeley software bug) 2. Boot in safemode. Hold shift during startup. This give a blinking screen of white with horizontal lines moving upwards until the login come. After login its alot of screen tearing when moving finder windows or similiar. (most likely software "bug") 3. Start migration assistant. When it started quit it directly and it goes back to a login screen. Login and you will see a flash of weird colors for a while. Sometimes they stay until restart. This is the worst one and can be indicator of hardware error. How many more get these? If you do get it, report it to apple support so they can fix it faster.. I tried 1 and 3 on display models in store and got same even..
