I also do not know about the code, but I tested ubuntu mate 18.04 and ibus. Here a similar menu appears, but there is no delay when typing and changing input method. Maybe it could be a hint to fix the bug.

To change the input method you press the selected key, and an indicator menu appears on-screen to indicate which language is selected next. The menu disapears after 2~3 seconds and during which time typing is blocked. If you type while the language input method menu is displayed, the menu will not disapear and stay as long as you type. The language input menu should not block typing, and the disapearance of the menu should not be delayed by typing.
