White blocks while scrolling

[GoCubsGo]

I've tried to think of the best way to explain this and I cannot grab a screen shot of it (tried). Oh and sorry I don't have a shot of the next iPhone or a question when it'll be released.

In iTunes, Safari, & Firefox I have noted some odd behavior as far as page rendering goes. I'll have the screen size set to anywhere from 1269x963 to 1530x1385. These are just random measurments of typical window sizes from time to time. Clearly they vary.

When I am scrolling up and down white blocks appear, they're dynamic really, flickering even. What I tried to do was mimic the behavior so that it could be understood. I noticed this day one but almost figured that was just how things were. I haven't ever noticed this on my old PowerBook. The number and placement of such boxes varies. I think it's how pages are being rendered but I am not sure.

If this is an issue I'm outside my 14-day window to return but I am certain it can be fixed so I'm not overly concerned. But I want to ask anyway.

Not knowing if my connection speed has anything to do with it, I'm posting the results from a speed test connected via ABES (wireless) through Time Warner.

Finally, I can say that this behavior isn't repeated if I take a screenshot, open in preview, size the window to around 1000x800 and scroll like a madwoman.

Any feedback is appreciated, even if you just want to say good morning.

Good Morning.

I can only say that this does not occur with me and therefore should be regarded as a problem. BTW I have the Radeon HD 2600 XT.

thank you. I will see if anyone else has feedback but sometime next week I'll call Apple and see what they have to say.

I too would be interested in Apple's explanation of this problem, I've noticed a similar issue on my newly purchased MacBook Pro. At first I thought that it was a Safari rendering error since it occurred in both Safari and in the iTunes Music Store, however I see this happening in the Finder when scrolling as well as in iPhoto.

It makes sense if its connected to graphics card but I'm hoping that I don't need to get a replacement.

If you are able to get an answer from Apple jessica. I would be interested to hear what they have to say.

Thanks

Note: I've noticed in Safari that once the whole page has been loaded the glitch does not appear until another page is accessed, it was this that had made me shift towards a rendering issue but of course I'm not certain.

Me Too-Wonder if It is Time to Blow Out the Dust?

Could this be caused by the video card overheating? I've got a 2.66 with the standard NVIDIA GeForce 7300 GT. The machine has been uploading for hours and I had been watching some You-Tube.
