5K light bleed (and lag)

I'm sorry, I have no idea why the photos are flipped. They're fine when I view them in Finder. Sorry. Working to fix them.
EDIT: It's fixed.
Simple stuff like web browsing, switching applications, and scrolling through images in finder. My Macbook Pro is an i7 Early 2011.
Wow that's pretty bad... looks even worse than mine. Very common issue on these, every one seems to have a little backlight bleed.
Same here
That is pretty much what I saw on the 5k iMac in the Apple store when deciding whether to buy or not. Try it with a grey bar screen as well.
What are the test conditions that you set up to get the screen to look like that? If I set the screen brightness to maximum and display a black background, I see a very faint amount of light in one corner. With brightness at viewing level, I see no leakage at all. This might be the best display I've owned for uniformity and light bleed.
I'd be willing to bet all Retina iMacs have some light bleed. It's really not noticeable 99.9% of the time, in normal viewing environments. The only time I really notice it is if the lights are pretty much off in the room I use mine, and I crank the brightness to max and view a black screen or very dark material.
I've had a bit in other iMacs, and other 2560 panels.
Don't seem to have it on my current riMac.
Wonder what causes it? Definitely reason to get a replacement IMHO.

Are you sure you don't have any backlight bleed? Mine has some, enough to be noticeable unfortunately. Not that I haven't been contemplating getting a replacement, but a replacement is just as likely to have this same problem.
No it's not. Pretty much all of them do it (if not all). Some people are more sensitive to it than others, and some displays are worse than others.
99% of the time the issue isn't visible.
the first screen looks really bad.
Macmee: You have got to be kidding, if thats the only amount of light bleed then you should seriously be happy with it.
After waiting 2 weeks, I got my iMac full specs retina and light bleed in the right top and bottom. Also what seems like marks under the screen panel most obvious when I drag windows left and right. eg.) safari with a white background. I'm not sure what it is.

Heres at full brightness
No lag whatsoever though. Great with maximum scaling and smooth at retina setting of 2560

I'm not returning it or anything, I just mean for the price we paid it's a damn shame there's this bleed, which I never experienced on lower resolution monitors from apple in the past, or on the rmbp.
Mostly it's annoying to me that some of us spent $4k on these and they were made in China and have faults in the displays, pretty lame.
agree. mine came up to about $5300 australian dollars. I would expect near perfection. When I first heard assembled in USA I was so glad and then found out they were being shipped out of china.
I have requested a new set and they have agreed. I was insistent that someone verify the screen was free from all deformities before sending it out to me.
The fact that something is made in China doesn't say anything about the quality. If Apple were to demand and pay for a certain quality then they would get it.
I have high quality gear that was made in China. It's not like they are bad at what they do, only that they often do not get the chance.
Im sure the camera exaggerates a bit but that black light bleeding on the right picture is the worst I have ever seen. I replaced my late 2012 rMBP (perfect screen) with the late 2013 rMBP and that had some bad backlight bleeding but nothing compared to yours. Mine was even noticable at 50% brightness so I took a picture and got the screen replaced at the genius bar, for free. I'm glad I took a picture since it's impossible to show them in the brightly lit Apple stores. The genius immediately, after seeing the picture, said that the bleed was too excessive. They will probably die when they see yours. Wow
Again all LCD normally have light leake in some form but yours is just insane. Exchange now
Those pics I posted were on a black background, 50% brightness. I'm actually returning the unit. Between the backlight issues and the lag, it's not worth it to me. The machine cost way too much to have these kinds of issues.
With 50% only, WOW. Than its 's by far the worst one I have ever seen, in regards to backlight bleeding. Get your exchange and don't forget to bring those pictures into the shop since it's hard to show them there.
I exchanged my iPad air 2 today for excessive backlight bleeding and they done an exchange after I showed them a picture (below), no questions asked. Their service as usual was amazing, I imagine especially when you will go with a very expensive 5k iMac.
The lag might be some optimisation problem in Yosemite, similar to when the first rMBP were released. They also lagged in the beginning but I'm not sure how bad your lag is, maybe it is a hardware defect.
