bad PNGs, thunderbird and firefox

[brian]

thunderbird-3.0-2.6.b3.fc11.i586
firefox-3.5.2-2.fc11.i586

Suddenly, most of the icons in thunderbird and *some* images in ff are 
pretty messed up. They appear to be indexed to just 3 colours. 
Sometimes, it's predominantly neon green, other times purple or black. 
In TB, it's the ones that are highlighted, except for folders, which 
look fine. Any icon that's greyed out also appears normal. Also, the 
icons in the "write" window i'm typing now in are ok.

In FF, there doesn't appear to be any rhyme or reason, save for the fact 
they're all PNGs. I thought that it was background images only, but that 
doesn't appear to be the case. Nor are all PNGs screwed up.

I recently installed an LCD display and so modified my xorg.conf. But 
this problem only just appeared so i doubt it's related. Is anyone else 
seeing something similar (it's *really* hard to miss).

Otherwise, can anyone think of what I can check?

Here's the latest from yum.log:

This really sound like an intermittent bug in firefox and thunderbird,
given the other information below.

Seems it isn't the video driver then.

Actually, it isn't.  From the mozilla web site,

http://kb.mozillazine.org/Safe_mode

Linux

On Linux, you can go to your Terminal and run (for Firefox):

        * /path/to/firefox/firefox -safe-mode 

It probably accepts the --safe-mode as well.  It isn't like Firefox 
is going to have lots of options from the command line anyway.  I was
just being peevish.

I'm not seeing this in FF, don't use TB (F11 x86_64).  It is probably
some obscure interaction between your hardware, its drivers,  and those
applications. i.e. a bug

Are the distortions consistent?  i.e. do the same icons and images
always have the same distortion?

What if you save an image that is distorted and open it with an image
viewer?  Still distorted?

Do you have any strange configuration options set?  Effects plugins
installed?  

What if you start firefox in safe mode?  
firefox -safe-mode  
(bad option design!).

Anyone? Is anbody seeing anything like this? I can't think of what to 
look for as *most* images look just fine. So, I can't imagine it's a 
problem with X.

Yes & no. Sometimes, both apps display things just fine. But, when they 
misbehave, it's always the same images. In TB, for instance, the images 
that are screewed up are the menu icons at top, except for the trash and 
printer. eg.

http://img89.imageshack.us/img89/6851/screenshot1ji.png

In the folders list, it's all of the icons except that for "Drafts" & 
folders. However, the manner of distortion changes slightly: sometimes 
everything is predominantly purple and other times kind of a caustic 
green. But it's always the same icons, which suggests to me that it's 
something specific to how those files are interpreted.

With FF, again, it's always the same images. The difference is that the 
icons are all fine and the problem is only with content images. Both PNG 
& JPG are affected (I haven't noticed any GIFs) so that's a bit confusing.

Note that FF has gone green while TB is purple today.

I opened an example image from FF in both GIMP and EoG and it was 
displayed fine.

No.

Once I came across a bad image in FF, I restarted in safe mode and 
browsed back to it. It was still bad. (It's "--safe-mode", btw)

I have not come across anything similar in any other apps.
