Launching application in Weston Kiosk from systemd service

Hi,

I am trying to launch an application in a Weston Kiosk using a Linux service (systemd or whatever). The purpose is to control the application from outside Weston (for example start and stop the application).

Without the kiosk mode, i launch the application using WAYLAND_DISPLAY env variable using a dedicated socket for my Weston instance => The application shows in Weston well. command example: WAYLAND_DISPLAY=/some/path/wayland-1 /some/command

With the kiosk mode enable, the application is started but not showing inside the Weston screen. Here is how I launch weston : weston --socket=/some/path/wayland-1 --shell=kiosk-shell.so

What am i doing wrong?

The weston version is 11.0.1.
