Product: Fedora https://bugzilla.redhat.com/show_bug.cgi?id=924046
--- Comment #2 from Peng Wu pwu@redhat.com --- I tried to build a upstream version of ibus, on: http://pwu.fedorapeople.org/ibus/ibus-1.5.1-3.fc20.src.rpm
It seems that the upstream tar ball still have similar problems, especially when: 1. Ctrl and Space key are pressed in the same time; 2. Space key is slightly pressed ahead of Ctrl key;
