@zyr123: It is also possible that it is just the newer graphics card driver.
Oh really?

And again a few years later.

I'm not saying that AMD's GPUs are innocent of all crimes, I'm saying your view is somewhat skewed.
Its probably a driver issue. I have not had any issues with my MBP yet. I would contact apple care though, They cant fix/report it if they don't know about it. Also start a thread on Apples forums. They do monitor them for new issues. If it gets traction there it will help.
I keep mine on the dedicated card all the time too. Haven't noticed any flickering.
OP, you're still within the 14 day return period...

I have the 2015 and haven't seen any lag or white flashes. It might be a problem with your specific machine.
If the system is doing its job right it should switch and not matter. But if there are tasks using the iGPU in theory they could run a bit better on the dGPU
It's not necessary to alter it's default setup. It will automatically switch to the discrete GPU when it needs to. If it doesn't switch, it's not needed (excluding bugs).
To be honest, I'm rather nervous about buying a dGPU equipped mac at this stage. I have to believe apple has gotten beyond the issues from the prior models but I can't be sure of that.
and that is why I bought the base model 2015 MBP with å 512GB disk..even when the cost difference between this and the and the one with the dGPU was a few bucks....Just not worth the risk. Having said that...the card usually fails after a couple of years....come back again in 2017

I don't see the problem here ...there is no way of knowing for sure it will fail, and if it does Apple will probably just give you a new one.
No harm no foul.
And 2010 as well with the GT330M. Many reported it to have intermittent black screens and constant crashes leading to a 3 year warranty extension on the logic board which ended in 2015. I personally prefer nvidia as well but it's not like going with nvidia would eliminate any issue.
I was hit with ATI failure with a 2002 iBook (there was an extended replacement programme for that) but I don't know whether it was the same root issue. All of my Macs have been ATI/AMD (not due to choice, but rather that's just what's been available at the time) and the iBook is the only one that ever failed on me. Even widespread problems only affect a small percentage of machines, so I didn't have any hesitation with buying a new one.
Please prove to me it's a design and/or manufacturing fault and not a software glitch or a single faulty Mac. I think it's more likely you are jumping to badly thought through conclusions based on paranoia!
We never saw 2002 iBooks, 2008 MBPs or the 2011 MBPs exhibiting similar faults within the first couple of days.
I just got a replacement 15" 2015 MBP 2.8Ghz. My 2011 17" MBP burned through three logic board replacements (because of Radeongate - three GPU/logic board failures). 
replaced it finally. Thank-you .
Since then, I have noticed a couple of screen "flashes" - but I think it's related to having Graphics Switching enabled. After running it with graphics switching disabled I haven't seen it. I don't have enough screen time to relax just yet though.
I also tried running Unigine Valley in Benchmark Mode and all I see is some graphics glitching on the transitions between scenes. The scenes themselves run flawlessly. I get 18 fps - 6fps results with an overall benchmark score of 452 after a few trials. The fans kick-in at about 87ºC and quickly run the temps down to 65ºC.
Running PS CC 2014 using Open CL2 doesn't seem to be a problem so far. All of these things provoked GPU anomaly/failures on my recently deceased 17" MBP so I'm okay with it - so far.

.IMO, it's obvious AMD was willing to bend over for Apple this time. Look at at the M290X, M2950 , and now the M370X. All Mac exclusive. I think Nvidia gave applethe finger (we have what, 10% of the desktop/laptop market) and maybe that's a good thing. My iMac 5K just plain purrs along. New MBP /w AMD GPU doing okay for a mid range GPU too (very impressed with the 295x in my iMac)
