--- Comment #5 from Attila Fidan winebugs@print0.net --- Oh, this is probably due to server-side key repeat. In retrospect, it was probably a really bad idea to have that upstreamed with the current state of wayland protocols/compositors if this will break certain kinds of games. Though, if you do not have an IME enabled I am surprised this behaviour exists in kwin. I'm not sure if it can be fixed except for reverting those commits or adding a way to tell drivers when it should enable/disable text input so it doesn't have to always be enabled.
