A white input bar appear when typing on keyboard while play game I have a problem everytime I play a game on my Mac, and try to use keyboard's alphabet characters, a white input bar appear on the bottom of the screen (and the character go there instead of to the game). What is it and how can I turn it off? Thank you very much

It like this
It happened to me when I use foreign keyboard. As soon as I switch the keyboard input back to "U.S" the input bar disappears. And it seems like it's associated with Finder.
