Recently, I think I have found the solution for this problem. I removed all files under ~/.cache/ibus/ and rebooted the system. In the past over two weeks, the problem never occurred.

During that period, keyboard input gets stuck in any window text input widgets, for example, typing letters, enter key, backspace, and moving input cursor with arrow keys. But with other window widget, for example, a video player in browser, the keys can still work (arrow keys for moving forward/backward, volume adjustment, space for pause/play, F-key for full screen mode).
