display anomalies

Apparently the moderators are all over this form and quick to remove any anti-apple sentiments, so everyone be careful. Apple obviously knows about this problem, it's also obviously very widespread, and something that Apple is hoping will just go away. Please help me in making sure that it doesn't just "go away". I want more than anything to be back to feeling good about Apple products.

That being said, I wouldn't be surprised if Leopard exacerbated an inherent hardware flaw; from the moment I installed it I could tell my notebook was working overtime to keep up. Also, let's seriously consider the temperatures we are talking about here - I'm surprised the tiny components inside of these notebooks last as long as they do in such constant heat.

Please remember to subscribe to this thread if your having the same problems so you dont miss any posts.:)

I unfortunate have this same problem now as well. It seemed to coincide with the most recent World of Warcraft patch (3.1) for some strange reason. All of a sudden I started getting freezes during the game which required me to manually shut down (hold the power button in). Then I started getting it after a minute or two of normal system use before I'd load any apps, and then it started happening during the boot screen even.

I made an appointment at the Apple store, even included this link in my reservation comments, and then went in. The error showed up even as he tried to boot, and he right away suggested that I send it in for repair with the flat rate ($300 for me) that someone else above mentioned, since I don't have Apple Care. It's now out and away, so hopefully when I get it back I can post success. I don't know what to tell people who have been told they have to replace the logic board for the $1200.

After been going around in the web looking about the freezes in my MBP, I found this thread. Very interesting...
My MPB started freezing while playing Videos at Hulu or playing Paradise Paintball. I could not figure out what was wrong.

Wow I have this exact problem, I think beginning when I installed leopard. The graphic artifacts happen constantly, although I do run webkit nightly builds it happens other places too. I dual boot ubuntu and it rarely ever has the straight lines across the screen and never freezes. The freezing on startup has gotten really bad, most often crashing right after the menu bar loads the mouse is moveable but everything else is unresonsive. For some reason today I booted up in safe mode by holding down shift at startup and it seemed problem free. I know that isn't a fix but maybe it will help someone reduce the bug.

Turns out booting in safe mode disables quartz extreme, amongst other things. Without booting in safe mode pasting this in the terminal wil turn off quartz extreme:

defaults write /Library/Preferences/com.apple.windowserver GLCompositor -dict tileHeight -int 0 tileWidth -int 0

and this turns it back on:

defaults delete /Library/Preferences/com.apple.windowserver GLCompositor

I also turned off the translucent menu bar in system preferences under desktop/screensaver since i've seen corrupted graphics there before.

Add me to the list. I had noticed the artifacts for some time, but I figured I would get to it eventually. Then I stumbled across this thread and realized I better take care of it before my AppleCare expires.

I just tried to take some screen shots of the line-type artifacts, and what I found interesting is that they lines do not show up if I use Capture to take a shot of just the window. In order to capture the lines, I have to choose Capture screen. With Capture Window, the shot of the window appears without any of the lines.

Weird!

Good luck. I hope you all find a reasonable way to resolve your issue.

Hi Damiii,

you are affected by our problem. But you may be interestet in a quick technical analysis here, thats all you must know about this problem.

Thank you MacUser128!

In your opinion, are Apple considering a free of charge repair program?

In Nvidia-boards bug, the repair program arrived after the confirmation by Nvidia.. Ati will ever admit the bug?

I finally got a screenshot of the lines. Most of the time they would vanish right as I took the shot. I was watching hulu and that made it flare up so I snapped a shot.

Yah thats nasty,

i gotta a folder full of screen grabs with lines across the screen.

I'm having the same problem, and it's been going on for months. I have an Intel CoreDuo that I purchased in October of 2006, and the System Profiler shows that it contains the Radeon X1600 graphics unit.

This defect sounds like it's affecting more than just one person---I'm glad I found this thread by running a Google search on the graphics adapter---and a $2+k piece of hardware should have a lifetime of greater than 2 years, so I hope Apple offers to fix these machines (without requiring Apple Care). I doubt I'll buy another Apple laptop to replace this one if not.

The crash that I'm experiencing also occurs at about 60C, with the same kinds of distortions as reported in the screenshots linked in this thread, and the distortions get roughly increasingly frequent and increasingly pervasive as the CPU heats up, ultimately leading to a crash. Once the system crashes, the mouse cursor is still responsive, but clicking or hitting the keyboard doesn't have any effect again. For a few seconds shortly after the crash, the cursor changes into the "busy/loading/whatever" spinning thingy, and then returns to normal (that is, the cursor returns to normal; the system is frozen and useless until I reboot it).

This is starting to make my computer completely useless.

I have yet to upgrade to 10.5.6, but from what I'm reading, I'm not optimistic. I will try upgrading later tonight (when it cools down in my apartment!)

Mine got similarly unusable as of late but turning off quartz extreme has really eliminated the problem without any noticable side effects. As I stated above paste this command in the terminal:

defaults write /Library/Preferences/com.apple.windowserver GLCompositor -dict tileHeight -int 0 tileWidth -int 0

I'm not saying this is an acceptable solution or anyway clears apple of blame (or ati) but if you are like me you have things to accomplish using your laptop.

Hi D.Spencer

Turn off the 3D capability of the device completely sounds like a good try, hope that the Problem only affects the 3D GPU part or the heat reduction is enough. We should look if this really works for everyone here in every state of error.

Also i will look which applications are not running with this option. VLC for Example is not willing to play any Video in that mode.

Thanks for the information you provided.
