u mean this is a known issue with safari ? .. i didnt try another browser yet but i will now .. but its never happened be4 as i remember but a couple of days ago and now and yes with safari .. maybe its the latest update ??
 
Happened a lot with Safari on my machine when I ran on battery power. Problem solved when I updated to 10.5.3 or 4 I don't remember.
 
Well its never happened with me before but nowdays , i'm on 10.5.4 - SafariVersion 3.1.2 (5525.20.1) .. not running on battery thu .
 
Yeah..I panicked when this happened to me the other day. I figured out it was Safari as it's not doing it in Opera or Firefox..
 
Was happening to me in Safari and Word after I came back from sleeping, but since the last update to the OS, I haven't had the problem.
 
I had the same problem and it quickly developed into a bigger issue effecting not only safari, but lots of other apps like iphoto and itunes. Apple replaced my computer with no questions when i showed them a video of what was happening (i was still within the 14 days and it was the second replacement).

Next time it happens open up iphoto or itunes and resize the window a bunch of times quickly and see if you get a garbled display.
 
this isn't a safari issue. like one of the previous posters stated, this happens in any application.

i have the same problem in firefox, address book, mail, safari, adium, FINDER, etc. essentially anything where you can scroll.

i'm currently on my 3rd mbp. apple has agreed to give me a new mbp whenever the next revision comes out since none of the software updates (10.5.3 and 10.5.4) didn't resolve the issue.
 
If it were an issue with the graphics card, the issue would not show up in a screenshot. The graphics card only controls what is output to a monitor, not what is output to a screenshot.

This sentence is very funny :confused: :eek:

This problem is related to the drivers. Apple shipped a notebook without being able to write proper drivers for the hw they chose. The drivers are lousy even after a graphics update and a couple of os revisions. Shame.

Glad to here Apple was responsive on this issue, as I'm taking in my MBP next week. This has become extremely annoying and, in my case, affects iPhoto, Finder, Safari, etc.

There's also a long discussion on Apple's forums about it here:

And how these guys with defective GPUs are taking screenshots and posting around this forum?

From that thread ... anyone care to comment?

Isn't it perfectly clear? YES -- the Leopard Graphics update ENABLED the extensive use of the GPU to support Quartz Extreme. This speeds up graphics operations, especially with compositing windows -- dramatically.

You can see this by using Quartz Debug to turn off Quartz Extreme. The bug WILL disappear -- along with your graphics performance.

There IS a connection with putting the MacBook Pro into "Safe" sleep mode. Something about this corrupts the GPU. Setting to "Quick" sleep mode helps for many, many users. But there may be other triggers for the defect yet undocumented.

No doubt Apple can reduce, delay or perhaps inhibit the defect, probably by limiting Quartz Extreme. But if this bug IS related to a defective GPU, then any software fix will never restore the amazing graphics performance we've all come to expect from the Leopard Graphics Update.

I have never seen Apple so tight-lipped about a wide-spread defect like this. That would tend to indicate it ISN'T just a software issue. Apple will most likely need to replace logic boards for thousands of users -- and that is a process that may be difficult to set up.

I have to say that I waited almost 10 years to buy my first laptop from Apple and now that I have done it I realize that I have a bomb ready to explode in my hands... Im disapointed. Im really concerned about this GPU issue, because here is not that easy to replace my MBP, if it would be the case... the nearest Apple Service is 800Km away from me, and they take so long to solve things... I cant wait 1 month or more to have my laptop fixed.

I'm glad this has come up, though sorry it is happening to others.
I posted, or attempted to post this issue some time back with my MacPro. It's about 12 weeks old and started probably a week after I got it. It was only happening in Safari then began in itunes. I am still running 10.5.3 so maybe the 10.5.4 update will help.

I've been meaning to call Apple, but now that someone has clearly outlined the issue I think I'll give them a call today and point them to the forum.

I thought it was a graphics card (I have the 8800), but I take it that it is not.
I'd like not to have to lug this thing back to the store, but if so, I guess I will.
 
So do you guys think this is only a start ?? .. actually its not happening anywhere so far only safari & only after sleep but nowhere else .

Ps: i have all the latest updates installed .
 
Just took mine into the Apple store yesterday. The guy at the genius bar was helpful but didn't seem to be knowledgeable about the problem even though I clearly demonstrated it. He rebooted to run some diagnostics and for some reason I wasn't able to reproduce the defect after the reboot. I'm not sure how long it takes the problem to show up. I definitely know it's worse when the machine is on battery power.

Anyway, he shipped it off for repair so we'll see what they do to it.

This issue has been known for months. And it is related to drivers. At least this is the most common interpretation. It might be it is wrong.

With 10.5.2 it was a nightmare. With 10.5.4 it is much better but some kind of graphics problems are still here. Sometimes you cannot scroll, you cannot read text, you cannot watch videos.

If you happen to work on a previous generation MBP with an ATI card you do realize that MacOS is NOT (yet) able to run a nVidia card. Sometimes it looks like MB's x3100 is more capable than a 8600.

Apple refuses to have their drivers developed by nVidia: this is the result. Would it be better? No one knows, but I need to reboot my machine every two or three days because graphics becomes lousy.

Apple is still used to PPC-like hw evolution. But on this side of the world hw runs.
