Please ignore the "thousands of colors" bit. This is more 24bit versus 32bit. And I'm not being literal; I have no way of counting the colors, so I'm using the terms approximately for effect.
Got a tip for us?

No, I can't screengrab it (which in itself is interesting). I'll mock something up tomorrow though to demonstrate/guide.
Gotcha! I mistyped above, sorry.If this turns out to be universal amongst '10 MBP's I've pretty much made up my mind to upgrade the RAM and HD on my 5,1 and save my money, possibly for an i7 iMac. Or even a low MP.
If you don't need the hi-res screen and slightly large battery, that would be my recommendation at this moment in time. Get a refurbed 5,1.
If I'm not mistaken, in general there should actually be no difference in color spectrum between 24-bit and 32-bit color since the extra 8-bits are not used to store colour information, but transparency and layering information.
I don't own a new MacBook Pro yet, but I don't remember seeing any noticeable difference when I played around with one in the store. If there is a difference it's probably has something to do with how Apple is wiring the GPU display outputs to connect to the display rather than something with the Intel IGP itself. Hopefully it can be fixed with a driver update though.

You know, I'm not so sure this would really be a reason to not get an 15" i%.
Think about it: the whole point of the Intel HD graphics is to conserve battery power and reduce power consumption. A loss in color definition might've been a calculated sacrifice of that. If and when you want the better accuracy, you switch over tot he nvidia card.
phewww!
that's the sound of that going over my head. at least it sounds a bit more optimistic
Afaik the panel at least in 13" and prob. in 15" too have only 6bit color depth (6bit per color, 18bit real) thus it wouldn't matter and it is very unlikely the color is 16bit. I guess it is some kind of a driver issue. If this messed up GPU auto switching technology was not implemented by some idiots maybe they switch to dGPU so often because the Intel HD drivers for OSX suck. In Linux Intel drivers are usually the best compared to others but maybe in OSX it is different.
Still really weird and definitely not a feature but a bug IMO, because whatever they keep pretending the Intel HD GPU is not that weak. It is not orders of magnitudes slower (than 9400M) anymore but more in the range of 20% slower which makes hardly a noticeable difference in 2D use.

any news on this? I noticed the same thing (slightly choppy gradients when using Intel graphics) happening to my MacBook Pro.. is it normal (MBP 17" i7) or a bug or something hardware related? I'd rather not replace my MBP again
Probably not - I'd certainly never noticed it in real use.
However, now that you know about it you'll be looking for it...
Do you think it's normal then? What I'd like to know is whether it is a software issue, a hardware issue or no issue at all (just part of the system) and if every MacBook Pro 2010 is affected?
Got the 15" i7 with standard res screen, checked those pics using the intel and then switching to the 330M and saw absolutely 0 difference. Same with the finder windows or bar ect. This is not an issue affecting all 2010 MBPs for all those starting to panic.
Has anyone checked their settings in System Preferences? On my MacBook, integrated graphics cannot be set to 16 bit at all, but discrete graphics can be switched to 16 bit.
32 bit graphics = 24 bit + 8 bit alpha channel for handling transparency. And you can't see the alpha channel.
I noticed the banding too when I'm using the Intel card. Very strange indeed...
Beforce I noticed that the banding vanished when the nVidia card is active, I always thought this was a result of the 18bit-panel used in the MBP. Apparently that's not the case and the Intel card/driver is at fault.

I just noticed that the gradient shadow of the windows is also a bit choppy on the Intel graphics. I looked on the apple.com Support site for any updates and found a 1.3 software update for the 2010 MacBook Pros 15 and 17 inch graphics switching feature, but installing the update did not fix the issue
are you guys keeping your affected MBPs or are you getting a replacement?
