Hi all, I just updated to Mavericks. It feels good but with some little annoying problems. This bothers me the most. In Mountain Lion zooming/scrolling in Preview does not blur the letters, but it now does in Mavericks. It seems that preview turns what's displaying to jpg during the zooming, and then turn it back to vector graphics. It is common on note-taking apps on iPads, but I didn't expect it also happens on Preview. Does anyone else have the same issue? I wonder if this is intended or will be fixed later?
