Copy my comments from bug #65489 as that bug is marked as duplicate of this bug now:
What Wenzhuo experienced here 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. The workaround I gave here only applys to SCIM. 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 -- scim input freezes in various applications https://launchpad.net/bugs/66104 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
