Unfortunately, the hardware acceleration makes the text rendering horrid. Text is less sharp, black text looks dark grey, the spacing of small fonts is compressed...I really found it unpleasant. Fortunately turning off the acceleration makes it look normal. I hope they can sort it out as it, as it sounds like a good move, but not at the expense of everyday readability.
Here is a comparison shot - not the best example, granted - normal is left, accelerated is right. Look at the H on line 5 - it fits the pixel grid normally, but doesn't with acceleration on.
