Obviously a very minor thing, not even an issue, I just happened to notice it this morning...I wonder what made them change that?

This will be fixed in the coming weeks, was an unintentional side effect of an update to the game's UI filtering. At the very least, chat should be easier to read!

If you really really can't stand it, in the meantime, you can change the filtering mode by typing '::uiquality 0' or '::uiquality 2' in the chat (0 looks worse, and 2 uses more CPU).
