Maybe try changing your rendering system?
Well, I was about to try that- but for some odd reason it's begun working again.
I'll try it the next time it happens, as I
know it'll happen again.
Edit: Tried that, still nothing. As a matter of fact, that transparent-chat texture glitch appeared again, LOL.
Maybe your keyboard isn't set up like the English standard keyboards so the game isn't recognizing it and seeing it as foreign.
I have used this computer for the longest time with FeralHeart [before the update] and have never had this problem before.
It
should be set up like the standard English keyboard, considering I am from the U.S and this computer was bought in the U.S, lol. It seems to 'flicker' though as, like I said to Arc, it just suddenly started working again. Don't really know why, but I know that it hasn't been fixed and that it'll happen again sometime in the future.
