That was my thinking too. Remember though that this is using WebKit from 
Qt 4.4. I tried a couple of them in WebKit trunk (which Qt 4.5 will be 
based on), and they look a lot better. I'll try to add an entry in the 
chart for trunk when I get the chance.

I agree. The reason the comparison is b/w is because these results come 
from our internal test system, which was built for regression testing of 
  pixel perfect drawing. I will see if I can hack something together for 
this specific case.

I'm going on a two week sick leave now though, so feel free to enhance 
on these results.
