Package: gnome-core Version: 1:3.22+9 Severity: important Dear Maintainer,
This problem occurs at least in Emacs and Lyx. In Lyx, when I input a vector such as a force ("F" with an arrow above) with "Alt+v F", a lot of "v" appear ("vvvvvvvvvvF" with an arrow above). The situation happens randomly yet has patterns. The bug usually occurs after typing some words. For example, if I type "asdf " a few times, and then type "Alt+v F", the situation happens. In Emacs, similar thing happens. If one scrolls down a long document in Emacs with "Page down" or "Ctrl+v", the screen rolls many time. It seems that this situation never happens at the first time but if one press "Page down" or "Ctrl+v" several times, the situation happens. Such a behavior surely a bug. And I think the bug will influence other applications as well.
