Build Identifier: 

I've seen many ugly behaviors regarding fonts since OpenGL layers were activated. This is the only one I know how to reproduce.

Setting layers.accelerate-all to false solves this.

Reproducible: Always

Steps to Reproduce:
1. Go in the adressbar
2. Type some letters to get enough suggestions
3. Scroll through them
Actual Results:  
Fonts look ugly

Expected Results:  
Fonts look good

same as bug 582223 ?

The result is the same but I don't think it's related to fixed backgrounds, this is why I created another bug.

Another way to reproduce:

1. Go to http://www.quirksmode.org/blog/archives/2010/10/click_event_del_1.html
2. Go to one of the comment with overflow: auto;
3. Scroll in it
Results:
Fonts look ugly in the scrolled area.

After a timeout, fonts look good again.
