Hi,

Just received my MBP 2nd replacement and I am facing the same issue AGAIN...
Basically when scrolling up or down in Safari or Mail some horizontals lines appear, like static pixels. It's difficult to explain really but very annoying...

Anyone else have the same issue? I dunno whether I should return it again..hassle as I have to wait 3 weeks again (Made to Order, French Keyboard, etc...) or maybe a software update will fix the issue?

I will try to record a video and post in youtube to let you see.
 
I am on my third Machine and they all do it. I also tested all three in the apple store and they all do it too. I wouldn't take it back just for that. I think they will fix it with a software update.
 
Anyone else have the same issue with their screen? Not sure if I want to take it back again now....
 
this has been happening since the last revision of the macBook Pros. it is a GPU error in the coding, the way that apple has coded it. we are hoping that Snow Leopard will fix it. just hold on until then.

im sure that :apple: + A will come in handy in the mean time :p
 
Are all new MBP's affected by this problem???... Hmm, I guess I should cancel my order...
 
my safari has the same issue...
here is what i noticed : if i'm turning my MBP on when it's cold, (e.g. 14-17C ) there are these "scrolling-lines "
but when i'm turning it on and the temperature is at 20C-25C, there are no lines at all...
not sure why it depends on the temperature...just an observation...

nevertheless, i think it's not a big deal...and i guess this can be completely solved with a software update...
and besides that, my mbp is perfect :)
 
Another piece of infornation regarding the issue: the problem does not exist with the web browser "OPERA"....strange stuff...

The phenomenon is usually called screen tearing.

I sometimes see this in Safari, but never in Firefox on my system. It is only real specific graphics that do it. As mentioned above, the older MBP (and even my old MB) had the same issue.

The graphic card is not the same but the description of the problem is identical to mine.


One more thing: I have email Steve Jobs yesterday and today an "Apple Executive Relations EMEA" called me to get more information about the issue, he was very nice and helpful, he arranged for DHL to collect the MBP so Apple in California can have a look at it. Excellent customer service, at least when we email Steve Jobs.

not really - if you read the discussion from Apple that you in fact posted, it tells you that the issue is caused by something called "coalesced updates" which is a "feature" of Webkit (the engine behind Safari and Firefox). It can be disabled in Firefox, and Opera doesn't use webkit. It's not a graphics card issue - just the way that the software tries to communicate with the graphics card. I'm not an expert, but from what I've read, it can occur on any mac. I had this issue a fair bit last week, but this week it's perfect, so there's nothing we can do really. Incidentally, do you still have it with the latest Safari update (as of today)?
 
What is it exactly?
I'm wondering if mine has it or not. What I expereince is when scrolling w/ the trackpad it seems a little blurry and possibly some thin pixelated lines....when I scroll in Safari using the arrow keys its rough & jumpy...

The thing is w/ my iMac scrolling is and has always been very smooth. Nothing is smooth about scrolling on any of the MBPs that I've tried. Is it a notebook thing?

nah you would know if you had it. imagine scrolling and seeing only the blue scroll bar move, and random big blobs of txt/graphics stay put when you scrolled. im talking up to 100px X 100px. its just like a jig saw puzzle on the screen!

It can be quite subtle actually.

Go to http://www.apple.com/ , with the picture of the MB and MBP, reduce your window size to 1/4 (roughly 640 x 480) and scroll up and down. You will (if you have the issue (which I suspect many do)) notice a minor line going horizontal across the screen while scrolling. You can actually scroll really slow, and still see the line.

It is also something a previous generation Powerbook stumbles on, so I believe it is more related to OS-X or our copy of Nvidia drivers.

oh i see, well that is nothing compared to the problems my gf has on her older gen 2008. the screen ends up all over the place...
 
Well if I have it then its the thin line, almost like a ripple in water...I can barely notice it but every now & then it catches my eye. Makes the scrolling appear not smooth. If its the big blobs of text then I don't have that problem.

So do ALL early & late MBPs have this issue? What about the MB & Air? I really hope this glitch is fixed, its minor but distracting nevertheless.
 
Hopefully not all the new MBP are affected.
Please post here as well so Apple support can have a look and bring solution or expected time of resolution via software update
