Hi,
I recently purchased a new 13" MBP with retina display and Intel Iris Graphics. Running the latest updateIt works great except for one tiny issue that doesn't affect performance but is slightly worrying.
Whenever I log in to an account for the first time, a grey screen with the apple logo appears briefly and then the screen takes on some weird distortion for a few seconds. The top 2/3 of the screen appears solid grey, the bottom 1/3 is white with some small blue dots, and there are about 6 or 7 horizontal dark grey bars (the same shade as the apple logo) that alternate from left to right across the center of the screen.
This only lasts for a second or two, then my desktop appears and everything works fine -- no other problems.
I have tried resetting SMC and PRAM/VRAM but the issue persists.
I have also tried running Apple Diagnostics by holding down the D key as my Mac restarts, but nothing happened. Possibly it is booting too fast? Something I never thought I would complain about, ha.
Any advice you can offer would be very much appreciated. I really hope there isn't a problem with the graphics card..
