XKB configuration is ignored

[SL-RU]

Bevy version

bevy = { version = "0.15.2", features = ["dynamic_linking", "wayland"] }

[Optional] Relevant system information

Arch Linux 6.12.10-zen1-1-zen. Wayland Sway WM.

What you did

I'm using xkb_file sway command to modify default keyboard layout, it includes swapping Ctrl with Caps Lock keys functionality. Every other application, games, steam games, wine and etc uses my overridden configuration. But bevy does not. So to be clear

Physical key	Key functionality
Ctrl	Caps Lock
Caps Lock	Ctrl

xkb file: https://github.com/SL-RU/i3config/blob/think/default.xkb

command to reproduce: swaymsg input '*' xkb_file ./default.xkb

What went wrong

When I press physical key CapsLock ButtonInput<KeyCode> receives press KeyCode::CapsLock and when I press physical key Ctrl ButtonInput<KeyCode> receives KeyCode::Ctrl`. So it is ignoring system setting and seems to be using some default xkb configuration

This is almost certainly driven by behavior in winit; can you reproduce it there and open a bug upstream, linking this issue?

The behavior you're observing is actually correct. The KeyboardInput struct contains both key_code and logical_key fields. The XKB configuration only affects the logical_key value while leaving the key_code unchanged. You can verify this yourself by running the keyboard_input_events example. I've also swapped Ctrl and CapsLock on my system; the example produces the results below:
