So after installing VS 2010 Beta 1 myself, I have to admit the blurry text is horrible. If you scroll a list that contains text, some of the text goes blurry, then after you stop scrolling, it slowly "fades" back into focus. Quite a nauseating effect. I really can't see myself staring at VS for 8+ hours a day the way it is now.
I logged a bug, even though there are already similar bugs logged, just to make sure this problem is not swept under the rug. But thanks to vesuvious's reply, it looks like this will be taken care of.
The other thing I noticed is that the whole IDE feels like a step backwards, in the sense that it feels like some sort of cheesy web app. Very clunky. Hopefully this is also due to it being an early beta and that things will get polished so that it at least doesn't feel like such a step backwards.
