Issue wit keyboard layout in Xwayland applications

[hownioni]

I've tested that this is not an issue with xwayland-satellite.
When starting xterm on DISPLAY=:0 (the one niri uses by default when starting xwayland-satellite and when running X11 apps) it doesn't adhere to the keyboard layout I've set on my config. I then run xwayland-satellite manually on the terminal and it starts a new instance on DISPLAY=:1, then I use the command env DISPLAY=:1 xterm and it does adhere to my keyboard layout. I've tested this on both a laptop using Latin American keymap and a desktop using US International keymap and in both instances the same happens.

In the end this issue was unrelated to niri. The solution is to check if you have fcitx5 on your system and either uninstall it or stop it from autostarting by default.
