As the discussion and tests in bug #66104 shows, what Wenzhuo experienced is a probably a well known (at least among input method people) bug. This bug usually shows up when user uses XIM (therefore using other GTK or Qt IM module seems to make this bug disappear), and is not restricted in GNOME. The discussions on SCIM mailing list and Redhat bugzilla suggest it is a bug in Xorg.
I've given a workaround in bug #66104, but only apply to SCIM users. This problem is more visible in Ubuntu than in Debian because Ubuntu's scim package set the /FrontEnd/X11/Dynamic configuration to false by default to get better support for deadkeys. Both upstream tarball and Debian package set this to true by default, and this bug won't show up in the default configuration. ** Bug watch added: Red Hat Bugzilla #201284 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=201284 ** Also affects: Fedora via https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=201284 Importance: Unknown Status: Unknown -- gnome-terminal tends to lock up https://launchpad.net/bugs/65489 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
