It wouldn’t be the launch of a first-generation Apple product without a few hiccups — who can forget Antennagate and Bendgate? — and the iPhone X is no different. A handful of users report that a mysterious and inextinguishable green line has appeared on their device’s display.

The above images, from Twitter users mix0mat0sis, Nate Heagy, and Christian Roman, represent a few of the examples of the “green line of death” as the latter called it. No one seems to know what causes it or how prevalent it actually is. I’ve asked Apple for comment.
