The only way to get the issue to reoccur again is to end the current desktop session (logout) and start a new one. (Re-login.) So although ibus seems to have something to do with it, ibus itself is not the direct cause of the issue.
To clarify: logout means end the current X11 desktop session. Exiting wine and restarting it doesn't cause the issue to reoccur after exiting and restarting ibus.
