Hi, This problem has existed as long as I can remember with pre-edit. So you first have to choose a MIM that uses pre-edit.
If you are trying to reproduce this it is easier to observe if you have pre-edit underlining enabled. Next, the sequence you type must result in an *uncompleted* pre-edit buffer. Then simply turn IBus off and the recently typed characters will disappear. cya, # -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
