Forgot to mention, the issue only happens in LibreOffice, not in other apps like Kate, Firefox...
Comment 2 trmdi 2026-01-12 10:44:56 UTC 
Sorry again, this issue happens when you use fcitx5-unikey and enable the option in the step 1.
Comment 3 Michael Weghorn 2026-01-22 11:24:57 UTC 
I tried to reproduce, but as already mentioned earlier in https://bugs.documentfoundation.org/show_bug.cgi?id=152519#c24 (that ticket also has more details on the setup), I cannot reproduce the problem  on Debian testing with current master, in a KDE Plasma Wayland session.

Can you please share the exact version information from "Help" -> "About LibreOffice" and your Linux distro?

Any ideas on what a relevant difference might be why I cannot reproduce the problem?

> 1. Enable the "Allow to modify surrounding text".

Don't know whether this is relevant, but in the fcitx5-unikey version provided by Debian testing (5.1.9-1) this is called "Allow to modify surrounding text (experimental)". What version of fcitx5-unikey are you using?

Comment 4 Michael Weghorn 2026-01-22 11:55:12 UTC 
Also, can you please try whether you encounter the issue also with the qt6 instead of the kf5 VCL plugin?

You can test that by setting environment variable SAL_USE_VCLPLUGIN=qt6 when starting LibreOffice.
Comment 5 Phoenix 2026-01-22 13:49:17 UTC 
"Spaces are removed" issue should happen on vcl gtk3 (Libreoffice on Gnome or KDE) only.
Comment 6 Phoenix 2026-01-22 13:56:47 UTC 
Edit:
"Spaces are removed" issue should happen on vcl gtk3 (Libreoffice on Gnome or Xfce) only.
Comment 7 trmdi 2026-01-23 09:05:48 UTC 
It also happens on with qt6 vcl.

Yes, that's it.

I'm using fcitx5-unikey 5.1.7 on openSUSE Tumbleweed KDE Live.
Comment 8 trmdi 2026-01-23 09:13:08 UTC 
"a b" => space is removed on wayland+kf5, not removed on wayland+qt6
Comment 9 trmdi 2026-01-23 09:19:35 UTC 
"a[space][backspace]f[space]b" => space before b is removed on both kf5/qt6 vcl.

It does not happen in Kate.
Expect "à b".
