    ui: Workaround conflict between repeated key swallowing and ibus
    
    Quote: """
    Some more debugging and it turns out that for whatever reason, ibus
    generates an extra keypress event for each letter pressed. The second
    event is caught by the "held key" detection feature of Kupfer (for
    launching default actions) and is getting swallowed.
    
    ...
    
    Since the time between the two events appears to be on the order of 1
    to 5 ms, attached is a patch that puts a minimum threshold on the
    repeat time.
    I have it set to 20ms, which is very safe for making sure ibus
    keypresses get through, although it will break things for people who
    have their repeat rate set to 50 Hz.
    The ideal patch would compare the delay to the current X11 repeat rate
    setting, but this gets things working.
