This is a follow-up to this post. I've come up with a very reliable way to reproduce a display issue on my machine. Could you help me test it and see whether you could reproduce it?
Steps:
Thanks so much!
Edit/Extra Notes: 1) I couldn't reproduce this issue at the Apple Store, but they were all running 10.15.1 while I'm on 10.15.2, so could be an issue introduced by the update. 2) Turning on True Tone also triggers the green lines. 3) When the MBP display is showing green lines, external displays look fine.
Steps:
- Turn ON Night Shift in the Display settings.
- Make sure your MBP is using the discrete GPU (launching Photos should do it).
- Download this html file and drag it into Safari (it's a simple html file showing two lines of text).
Thanks so much!
