After gaining extensive experience with Aster and managing multiple complex configurations, I've encountered a new issue that I'm unable to resolve.
Configuration:
- A computer with two sessions/screens, with Aster installed and configured.
- One Xbox controller associated exclusively with one session.

Steps to Reproduce:
- Run a game on the first session/screen using Steam with the controller; everything runs fine. (1.2 - "Salon" in screenshot)
- Simultaneously, launch Steam Big Picture on the second session: the cursor moves without any keyboard/mouse action. In fact, Steam Big Picture is being controlled by the controller from the first session! It seems the controller is sending actions to both sessions. If a game is launched through Big Picture, the controller from the first session also controls the game on the second session. (1.1 - "Bureau" in screenshot)
Without Big Picture, everything runs fine. Has anyone else faced this situation before?
Thanks in advance for your time !
