Well I will switch to any browser that has the same performance as Chrome has also didn't have this issue. So annoying. But Chrome (I use the Beta one) is the fastest browser in KitKat I would say. It's not like another browser wasn't good, but chrome is really fast and smooth. Naked Browser is great but I hate it's interface. Too ugly.
P/S: whenever you want to get out of that font issue, switch to landscape and then switch back. It's gone right away for me
