Color fades when scrolling in Safari 4

Repairing the permissions fixes it until I lock my computer again using fast user switching. Any ideas on why this is problem now and it wasn't in the beta?
Any suggestions to prevent fast user switching from breaking my permissions?

Confirmed that: the colors go whacky again when I use Fast User Switching, too. Ugh.

I used Fast User Switching and tried the scrolling again, both in the account I switched to, and when I switched back but could not reproduce it. I also went into sleep and back again, but still everything was OK. Did you restart after running Repair Permissions? I haven't done this, but maybe it helps for you.

I take it all back!

This morning the problem is back again.

Has anyone else had Repair Permissions work at first but then later have the problem come back? Because that's what's happened to me.

Had you used Fast User Switching to lock the screen or put the computer to sleep after repairing permissions?

here's what mine looks like - and on this very page:

Yes! One of my kids was on it after me, and we put it to sleep when she was still logged in.

Hmm...

Maybe putting it to sleep does it, too?

Hmm? I just cured it again but in a different way.

I'm on dual screens (second screen is a 22" Benq).

This time I dragged my Safari from the Benq (which is my main screen) to the iMac screen and tried it. No probs! However, when I dragged it back to my Benq, it also no longer has the problem.

Dunno how long this will last of course.

I'll go try some Fast User Switching and some Sleeping.

Ok. Sleep didn't bring the problem back, but Fast User Switching did. All I did was switch to the login window and it came.

Now to cure it again....

Ok. Worked again. Dragged the Safari window to my iMac's screen and back again and the problem has gone away.

Just as a test, I also tried dragging only on my Benq screen but that didn't work. Nor did switching off Spaces.

So, quick fix (until your next FUS), is to drag the Safari window to another screen and back.

Is everyone else with this problem using dual screens?

Oh, thank goodness for this - I thought I was going mad. Yes, I seem to be experiencing exactly the same thing. Colours look good when they first appear on-screen but they fade to almost greyscale as the page is scrolled.

As a matter of fact, switching to another user and back didn't show the problem. Looking back at my configuration at that time: the external screen was not attached. Over lunchtime, I went to the Login Window using Fast User Switching with the external screen attached to my Macbook Pro and it re-appeared when I came back to my session. Your workaround of dragging to the other screen and back cured it for now.

I filed a bug report at http://bugreporter.apple.com: bug ID# 6963632

I have the same problem. Repairing disk permission didn't help.

this started happening to me yesterday, but i had already been running safari 4 (final) for about 24 hours. i seemed to start soon after i upgraded cosmopod, so i don't know if there is a connection.

the repair permissions fix worked fine for me (so far), but now it just happened when i was in the finder! I clicked to open a word document, and half of my finder window where the document was became washed out and fuzzy.

this seems like a serious issue going on.
