Invalid text in KeyEvent on Linux after recent change

[Riateche]

KeyEvent::text always contains a lowercase Latin letter, even if the current layout uses another language. Pressing Shift while typing still produces a lowercase letter. This issue first appeared in bb9b629.

Confirmed this issue on my end. Standby for a fix.

This code appears to be the issue, as it appears that reverting it to the old implementation of select_xkb_events fixes the issue.

winit/src/platform_impl/linux/x11/util/input.rs

Lines 36 to 67 in 8fdd81e

	pub fn select_xkb_events(
	&self,
	device_id: xkb::DeviceSpec,
	mask: xkb::EventType,
	) -> Result<bool, X11Error> {
	let result = self
	.xcb_connection()
	.xkb_select_events(
	device_id,
	xkb::EventType::from(0u8),
	mask,
	xkb::MapPart::from(u16::from(mask)),
	xkb::MapPart::EXPLICIT_COMPONENTS
	| xkb::MapPart::KEY_ACTIONS
	| xkb::MapPart::KEY_BEHAVIORS
	| xkb::MapPart::VIRTUAL_MODS
	| xkb::MapPart::MODIFIER_MAP
	| xkb::MapPart::VIRTUAL_MOD_MAP,
	&xkb::SelectEventsAux::new(),
	)
	.map_err(ReplyError::from)
	.and_then(|x| x.check());
	match result {
	Ok(()) => Ok(true),
	Err(ReplyError::ConnectionError(ConnectionError::UnsupportedExtension)) => {
	error!("Could not select XKB events: The XKB extension is not initialized!");
	Ok(false)
	}
	Err(e) => Err(e.into()),
	}
	}

@notgull maybe the keymap stuff is not delivered?

I tried putting an explicit synchronization between the server and client before/after the event call, but nothing changes. My current working theory is that the XkbUseExtension internal function is doing something else that I don't quite understand yet.
