Bug#893956: gnome-core: One click results in inputting many times

[Lu Wang]

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.

Best Regards

Lu Wang
