The problem is not bionic specific (ibus 1.5.17). Myself has confirmed it both on 19.04 (with ibus 1.5.19) and 19.10 (with ibus 1.5.21).
So the upstream commit which was backported breaks Qt, and AFAIK the problem hasn't been resolved upstream yet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1844853 Title: IBus no longer works in Qt applications after upgrade Status in ibus: New Status in ibus package in Ubuntu: Confirmed Bug description: Kubuntu Release 18.04.3 LTS Expected behavior: ibus continues working as before after applying security update 1.5.17-ubuntu5.1 from version 1.5.17-ubuntu5. Observed behavior: ibus is not usable anymore in Qt applications. After updating ibus and the related packages ibus-gtk, ibus-gtk3, libibus-1.0-5 and gir1.2-ibus-1.0 all from version 1.5.17-ubuntu5 to 1.5.17-ubuntu5.1, I can no longer use ibus in Qt applications. Using shift-space no longer changes the selected input method and even when i switch to the mozc input method in a gtk application, i can not use it in any Qt applications. When starting qtconfig in a terminal, I also get the following message: Bus::open: Connect ibus failed! IBusInputContext::createInputContext: no connection to ibus-daemon This bug was not present in version 1.5.17-3ubuntu5 and I also confirmed that downgrading the packages to version 1.5.17-3ubuntu4 restores ibus functionality in Qt applications.
