    I received my new MacBook Pro (15", 2.9 GHz, 1 TB, 16 GB, 460 GPU) earlier today and I have encountered two problems so far.

    1) The first problem is that every time when I login the lower part of the screen swiftly flashes for a fraction of a second. I have tried reseting the NVRAM, restarting the computer several times, and I have even formatted the disk and reinstalled the OS but the problem persists. Here is a video (at 00:06) displaying the problem (sorry for the obnoxious watermark):

    2) The second problem that I have encountered is a strange buzzing noise coming from under the (right part of) the keyboard. This has 'only' happened three times, but each time it sounded for about 2-3 minutes. Unfortunately I didn't think of recording the sound at the time, so I don't have any video of that.

    Have anyone experienced any similar problems? And do you perhaps have any thoughts on what might be causing this and any recommendations as to how I can fix the problems (if it is software related)?

    I don't know what that flashing at the bottom of the screen is, but I have it too. Have seen it several times before as well in this forum. Maybe it's normal? It happens every time and despite that the screen seems perfect.

    Edit: I have not encountered any buzzing noise yet. But the first problem really interests me.

    Thank you for your reply. It is 'good' to know that at least I am not alone. Perhaps you are right in that it might be normal. I chatted with Apple's customer service a while ago regarding the first problem, and they just replied that I might as well return it and get a new one (but they didn't say if they are aware of other people having the same problem or the cause of it).

    I am in London though, and unlike some Apple stores in the US the Apple stores here do not have any touchbar 15" MBPs in stock (as of now), so even if I would like to I am not able to exchange it for another one at the moment.

    As you mentioned though, the screen seems to be perfect in every other way. I just hope that the screen flashing when logging isn't a sign of something about to break down further down the road.

    I've seen some glitches when running Parallels full screen. My bet is that it's all software and will be fixed in time.

    Exactly. I can't really exchange mine because here in Germany they don't even have stock models yet (not many at least) and I would probably need to wait a long time for a BTO replacement. Keeping it for now and hopefully this will be fixed with a new software update.

    Thanks for the video, hopefully it gets some attention and others are seeing the same thing (as I mentioned, mine looks exactly the same at the same time of logging in).

    I have the exact same startup glitch except once the glitch occurs the whole screen turns black except for the progress bar... I'm hoping its fine!

    I also had a kernel panic this morning which is worrying me more - everything else about this machine is perfect, so I really am hoping it's just a software issue...

    Do you have FileVault encryption turned on? I had that same glitch and asked in another thread and others said it was the reason for that happening every login. Apparently that's the norm.

    Do you have file vault encryption enabled

    I just got my 2016 15 with the radeon 450 and have noticed some glitching. Not consistently, but a few times I have seen the screen flash. I have also noticed that with automatic graphics switching turned on, that the interface, opening new tabs, closing a tab, and opening up safari do not run smoothly at all on the integrated graphics 530. Not sure if this is prevalent as well. Hope your issue gets resolved

    That is interesting. Yes, FileVault encryption is turned on at the moment. If it is the norm then hopefully Apple will come out with a software update that will fix the problem.

    I just hope that the buzzing noises that I heard earlier today won't come back. The customer service mentioned that I could try reseting SMC to fix the noise, which I have done now, but it is too early to tell if it worked or not as the noise was inconsistent to begin with. =)

    I had/have the same problem and it is not restricted to the 460. It happens if you have File Vault turned on.

    I picked up a 15" with the 460 last week and had the same problem. I though it was a 460 problem so I returned it. Today I picked up a 15" with the 455 graphics chip as I could not wait for a BTO to arrive. Same problem. Saw another thread that mentioned the problem was tied to File Vault so I turned off File Vault and the problem went away. Turn it back on and the problem reappeared.

    Okay, so that more or less confirms the cause of the first problem. After some further investigation it seems as if the second problem that I have experienced with the buzzing noise might be due to the fan not being installed properly or something of that sort. The noise seems to correlate with the temperature of the computer, and it only starts when the fans rev up. I should probably exchange/return it as soon as the stores in London get stock. It feels ridiculous to spend $4000 on a computer with so many bugs and problems, and to not be able to exchange it immediately is really bad.
