Anyone seen it before? It's about 10mm wide all the way around the screen edge on my late 2015 27" 5K. It started the last few months and seems to be getting worse. It's 2 1/2 years old. Lucky i bought AC as Apple are sending a tech a 4 hour drive to replace the screen on Monday.
Gotta love their service.
