Bevy version

11d1ebe

Relevant system information

  • Running Linux, happens on both wayland and X11 (trough xwayland).

What you did

With a controller connected run:

cargo run --example gamepad_viewer

When no controller is connected it starts correctly. When multiple controllers are detected it also crashes.

What went wrong

The app immediately exited
