Weird - Safari re-rendering text?

[chuges]

When I visit certain websites, Safari loads up normally and then after about a second, the text on the website becomes slightly distorted/thinner. This doesn't happen for all sites (facebook, macrumors, gmail are fine), but it happens for enough random sites that I think it's a Safari rendering issue as opposed to a site-specific problem.

Example 1:


Example 2:


Whenever I visit yahoo for example, I'll see "Example 1" briefly before the screen changes it to "Example 2." I prefer the first image because it looks bolder and clearer, so if this is a rendering feature of Safari, I would consider turning it off for annoyance/aesthetic reasons. Both screen shots were also taken at exactly the same size - i didn't expand one to make it the same size as the other (hence changing the look of the text).

Anyone know why this is happening or have any insights?

I'm running a 2008 aluminum macbook on the latest versions of snow leopard and safari.

Thanks!

I've seen this happen on a forum where people can embed YouTube videos; pages containing videos have this "re-rendering" issue. Are there any YouTube or Flash elements on the page?

Not to my knowledge, although there could've been small flash advertisements or something on the side or bottom.

I also tried going to the same sites using chrome + firefox and didn't have the same issue, so I think it's definitely a safari issue

anyone else know anything about this?

I have the same issue in one of my WordPress themes, it happens only on pages with embed flash videos. I remember reading an article somewhere that this issue have been fixed in newer versions of Webkit, so I hope we will see it fixed in future major Safari update.
