Color fades when scrolling in Safari 4

Same here,
- MBP
- Dual Displays
- Fast User Switching is ON
- 10.5.7
- Safari 4.0.1

Hope Apple fix this soon!

I thought I was going nuts... Can't believe this hasn't been acknowledged as a defect yet.

I was having this problem just now - Dual screens on MBP with fast user switching enabled, but only logged in to computer with the one account.

I have fixed this by moving the safari screen on to my second monitor and attempting to scroll there. The colours didn't change on the external monitor. I have moved my safari screen back to the primary monitor and it's behaving fine now.

I am suspecting a coloursync issue. Next time someone is seeing this can you try switching coloursync (colorsync?) profile to a new one and then back again...

I too am experiencing the same problem with my newly bought 15 inch macbook pro.
I have a Dell 2407 monitor connected to my mbp and whenever I use the Fast User Switch feature,
I can see the colors going crazy as I scroll.

I was tweaking with the display color profile and if I choose the profile that came with the macbook pre installed and not the one I installed, the problem's gone. I've tested this a couple of times and the problem really seems to go away.

Can anyone else test this to see if this really works?

It does look like the issue has something to do with colour profiles associated with your display - moving the Safari window from one display to another would cause the OS to have to change how it is shown using the colour profile for the other display. However, I certainly would not disable my current colour profile for my MacBook Pro's display simply because I need it to be correctly calibrated.

Safari 4.0.2 doesn't make the bug go away but it changes the behaviour of the color fading.

Before I had only color fading on scrolling down, now I have the issue scrolling down or up. And before, the colors would fade until the text disappear, now it fades less, but it's still annoying.

I was really hoping that safari 4.0.2 would fix the problem, but I guess not. I haven't confirmed this myself but will try it out when I get home.

I got the solution (for calibrated screens, tested with Safari 4.0.2)!!!

1) Open Safari in a site that scrolls
2) Use fast user switch
3) Come back to your session
4) Scroll in Safari, the nasty bug is here
5) Now open System Preferences -> Displays -> Color
6) Switch the color profile to the default one (not calibrated)
7) Use fast user switch
8) Come back to your session
9) Scroll in Safari, the nasty bug is over
10) Open System Preferences -> Displays -> Color
11) Switch back the color profile to the one you was using
12) Use fast user switch
13) Come back to your session
14) Scroll in Safari, the nasty is not back!

I've not actually seen this until today. My machine in fine, but one of the work machines has now done it also:

MacBook Pro 2.0GHz
Fast User Switching ON
Safari 4 (up to date)
Leopard
Multiple displays

It says this question is answered... is doing a bunch of stuff with color profiles the "answer"? If that's not it did I miss the answer? I can't seem to pin it down. It is really shameful apple let this bug through. I switch to Firefox today.

A simple permissions repair seems to have fixed the only machine I have seen with this issue.

I can confirm that Repair Permissions does not fix the problem for me. As far as I am concerned this issue is both current and unanswered.

Agreed. The steps where you change the color profile didn't seem to work either.

I would like to add that in my case the window's frame is also affected. The change isn't nearly as dramatic but when I look closely I can see that the colors have faded slightly in the window's close, minimize and zoom buttons.

What ever the problem is, it's not in the page rendering.

I'm curious... How many of us have safari's debug menu enabled? (I don't mean the develop menu)

I quit Safari, removed the debug menu, re-launched Safari. FUSed to second user, FUSed back to first user...

no more color fade.

Probably just temporary, but I thought I would let you know.
