Linux: SDL_SCANCODE_LGUI, SDL_GetKeyboardState

[agreppin]

SDL release-3.2.4:

1. I don't receive any event with SDL_SCANCODE_LGUI.
2. ks = SDL_GetKeyboardState(&n), ks[SDL_SCANCODE_LGUI] is never set

Tested on Ubuntu 24.04.1 LTS, Wayland, pressing LGUI+F3 or LGUI-i
Note: emacs-gtk says those keys are undefined, so not bound to the window manager.

Edit 1:
ks[SDL_SCANCODE_LGUI] is set when pressing CTRL+LGUI

Out of curiosity, does the key event arrive if you call SDL_SetWindowKeyboardGrab() on your window? Even if the keys are undefined, something might still be eating the key press before it reaches your app/game.
