Seemingly random bits of text are kinda ugly/different, maybe where it hangs? Particularly when PDF is view in Evince.
If you mean slightly wrong anti aliasing then yes I noticed that, and I'm not sure it's related, probably it's the way pdf it's generated. Could you check how a pdf generated in Windows looks in your viewer?
