Same here with the fuzziness on some of the text on some tiles. Although I'm thinking it's just the tiles that are Microsoft apps (weather, stocks, etc.) that haven't updated through the store yet. However, I would like to have the option for 3 columns back (hope it's a bug) as the small tiles are now way too tiny honestly. And the largest tile really isn't all that "large". If it wasn't on the 6 inch phone, I would be highly annoyed. I'm now reluctant to put my wife's 830 on Windows 10 (even though I know she'd enjoy it) simply because I know her first complaint would be how small the tiles were.
