Hello,

お世話になっております。

Time to time I have to write in Japanese on KDE Neon, and for that I have installed fcitx and fcitx-mozc, and configured it with

Code: Select all

im-config -n fcitx

Everything was basically working out of the box until recently (no idea on precise time), when I have noticed that fcitx have stopped working in Qt apps like Kate or Konsole etc, while still working in gtk apps like LibreOffice and Firefox.

Any suggestions where to check if my environment variables are set correctly or am I missing some packages?
Or perhaps qt was updated recently, but fcitx did not follow?

Here is my fcitx-diagnose output:

Do you have a file called ".xinputrc" in your home directory? It should contain the following line of code:

Code: Select all

run_im fcitx

I had to manually create this file. Before I created it, Japanese input worked in Firefox, but not in Kate or kwrite.

I do, and it was generated by im-config.
So it must be something else.

Oh man, thank you so much. Now I can type Vietnamese in qt5 app, don't think the solution is so so simple like that. But after this fix, my fcitx systray icon becomes so weird and look ugly. How can I change it's icon?
