unable to use keyboard after starting .desktop with environment variable

[pltrz]

I use a window manager who's binary is called river. In order for me to also use an alternative keyboard layout, I configure this through the following environment variable, and immediately execute it:

env XKB_DEFAULT_LAYOUT="us(dvorak)" river

When I try to use this technique via emptty using the following river.desktop file, I am seemingly unable to activate any of my keys:

[Desktop Entry]
Name=River
Comment=A dynamic tiling Wayland compositor
Exec=env XKB_DEFAULT_LAYOUT="us(dvorak)" river
Type=Application
Environment=wayland

I am not sure which part of the stack is misconfigured.

Can you, please, provide your /etc/emptty/conf, if there is something changed? Have you tried to echo (if possible) on your variable XKB_DEFAULT_LAYOUT? Check, if the quotes does not cause the issue.

And to be sure, I see that river uses wlroots, which should support XKB_DEFAULT_LAYOUT, but did it worked with different display manager (not just being started from TTY)?
