Colors changing

I also have this problem, it's worse when a scroll slowly, and disappears when I scroll quickly.

- MacBook Pro 15
- 24" LED (symptom also appears without external display)
- Updates are latest greatest (10.6.2)
- Daylite and Omnifocus plug-ins installed (uninstalling these plug-ins has no effect)

I am having the same issue as *Brian Spolarich*:

"...If I read messages in Mac Mail and I scroll through the message body, any color elements (links, pictures, etc.) get gradually desaturated to the point that all color disappears. This only happens in Mail and only when I'm using the external monitor. If I just rock back and forth on the scroll wheel the portion of the message in the viewer eventually becomes grayscale. If I scroll down farther the color returns to the part above the top of the viewer pane, and if I click on another message and return to the same message the color returns, until I scroll..."

I am also on a Dell 24" monitor. Mail works fine when I am just working on my MBP.

Odd problem indeed :/

Just wanted to add I don't have this problem when I connect to my Apple 24" LED.

I am also having this problem. Just happened for the first time about an hour ago. I was using an external monitor earlier today, but the problem didn't occur until after the disconnect. I'm definitely getting that photo issue with the RSS feeds in my mailbox, but no problems with the rest of the mail..

I've had this problem for weeks and it's been fairly a consistent nuisance on my external display, but only when in Mail.

Yesterday, I saw the behavior in a Finder window on my laptop screen when not connected to my external.

Today I spoke with Apple care...we tried changing the Profile in Preferences | Displays | Color from "Cinema HD" to "Display" and for the moment things seem back to normal.

Perhaps folks on this thread can try changing their Color profile and seeing if this helps or not.

I will check back to this thread and update all if changing my profile actually 'fixed' things and if this issue still appears intermittently in Finder when not attached to my external display.

I have this problem as well. I've seen it in itunes and Mail when scrolling. In itunes, the gray lines become cyan. In mail, The colors of html content are altered. It does this on my original Macbook pro screen or/and the external monitor. It doesn't matter if an external monitor is plugged.

MacBook pro 2.2, 4 Go RAM, OS 10.6.2

I seem to have fixed this problem on my MacBook Pro - Restarting into SafeBoot (hold shift down on restart) - then restarting normally once repairs have been completed - seems to fix it.

Apple did advise this fix for iWork and iWeb crashes - apparently this removes font caches and forces creation of new caches.

This fix also seems to have fixed a problem with crashes on FileMaker Pro RunTime solutions.

I had this problem and quitting and restarting Mail fixed it. It was just in Mail. Mail was fine and then it just started doing this.

I took pictures in case they're helpful. The colors slowly cycle from what they should be as I scroll with either two fingers or the scroll bar. If I scroll back up it starts good again and cycles to bad.

After a frustrating call with Apple support I think I am a step further in analysing this. My MBP has 2 GPU's (NVidea GeForce 9400M and a NVidea GeForce 9600M GT), this problem only seems to occur when I use my 9400M.

I changed the power-saving settings to "Higher performance" to switch to the 9600M GT, and now the problem does not appear anymore.

After discussing this with some technical friends, it looks like there is a frame-buffer in the 9400M GPU, because when you scroll the colors get mis-alligned over the currently shown colors which are in the buffer.

I'll be contacting my local support company to discuss this and see if it is a production fault on the Apple side, and if they can help to get focus on this problem with Apple. As I could not do this during my support call.

Hopefully it is just a firmware problem, but it might be a defective hardware problem.

P.S. If you reply, please mention your GPU (Hardware>Graphics in System Profiler)

Hi,

I have suffered from this for a few weeks. I don't remember exactly when it started. This happens with my MacBook Pro late 2007, thus my video processor is GeForce 8600M GT. This may be relevant as recent posts mention the problem occurring when one of their 2 possible video processor is used.

The problem occurs on my internal monitor, I don't remember seeing it on my external (but can't be sure). It happens during slow scrolling, either using the trackpad (2 fingers) or a mouse's scroll wheel.

I don't have the problem on a recent iMac (latest 20.5 inch model) running 10.6.2 as well.

Count me in on this problem. Jumps up from time to time. Don't have a clue as to it's cause. Bright Green and Pink in Message Viewer, scrolling has some effect.

According to reports in MacRumours - the next release of OSX will fix this problem.
