Black bar across bottom of mail display
Yesterday, my email display started showing a black bar across the bottom, so the displayed list of emails is effectively shorter. No idea why this started happening. Only clue (maybe) is that I was using FaceTime before it started happening, but could just be a coincidence.
I’ve tried rebooting, but it doesn’t help. Another detail: the display is fine when I first open the mail app, then it shrinks up from the bottom pretty quickly, leaving a black space at the bottom.
