Created attachment 1888253 [details] Video showing the the conversion region is visible in some places but invisible in konsole, kwrite, kate Using Fedora-Workstation-Live-x86_64-36-1.2.iso installed in qemu-kvm with all current updates. kwrite, kate, and konsole, do not show the conversion region when using ibus-anthy konsole5-22.04.1-1.fc36.x86_64 kwrite-22.04.1-1.fc36.x86_64 kate-21.12.2-1.fc36.x86_64 It does not matter whether these programs are used in Plasma(X11), Plasma(Wayland), Gnome(Xorg), Gnome(Wayland), the behaviour is always the same, the conversion region is never visible. In konsole the behaviour is even worse because not even the cursor is shown at the start of the conversion region. When testing in Plasma(Wayland) or Plasma(X11) and typing with ibus-anthy into the search field of the KDE control center, the conversion region is coloured and thus visible. It is also visible when typing into the entry field for a command which opens with Alt+F2. So there are only some programs in KDE where it does not work like konsole, kwrite, kate, ... whereas it works in other places. See the attached video.
Seems totem does not have the codec. Which application do you use your attached video?
This message is a reminder that Fedora Linux 36 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 36 on 2023-05-16.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 36 is end of life.

(In reply to Mike FABIAN from comment #0) > It does not matter whether these programs are used in > Plasma(X11), Plasma(Wayland), Gnome(Xorg), Gnome(Wayland), the behaviour is I cannot reproduce your issue in Plasma X11. Probably you could exit ibus-daemon and run ibus-daemon again by manual and ibus-ui-gtk3 should be used. Wayland color issue has been reported separately and known issue.
I can still reproduce this exactly as before in Plasma X11 on Fedora 38. $ rpm -q konsole5 kwrite kate konsole5-22.12.3-1.fc38.x86_64 kwrite-22.12.3-1.fc38.x86_64 kate-22.12.3-1.fc38.x86_64 I don't think it is an ibus problem though as it seem to affect onl konsole5, kwrite, and kate.
OK, I didn't understand in what you meant the conversion region even though I watched your movie. Now I understood you meant the pre-edit segment color against whole the pre-edit color.
I confirmed this issue does not happen with qtbase/examples/widgets/mainwindows/application with qtbase upstream. This issue might be caused by kwrite or konsole. Transferring to kwrite
