fcitx5 input method not avaliable in bottles

[yikerman]

I'm on the following system:

Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.2
Kernel Version: 6.13.9-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
...

with my fcitx5 and rime installed with

sudo dnf install fcitx5 fcitx5-chinese-addons fcitx5-rime

and configured via ~/.xprofile:

export XMODIFIERS=@im=fcitx5
export GTK_IM_MODULE=fcitx5
export QT_IM_MODULE=fcitx5

I installed Bottles from flathub, am currently using ge-proton9-27 with everything else untouched. My fcitx5-rime is not working inside wine applications, that is, the input is always English ignoring my custom input method. I've tried passing the above variables to Settings -> Compatibility -> Environment Variables but had no luck. I also tried soda-9.0-1, sys-wine-10.0 and they yielded the same result.

I only tried soda as runner, but I solved this by adding env var XMODIFIERS=@im=fcitx5 to Bottles via Flatseal.

I suppose you can also do it with flatpak command

flatpak override --env=XMODIFIERS=@im=fcitx5 com.usebottles.bottles
