How to reproduce

Didn't figure out how to reproduce, maybe it's required to go into suspend mode.
Will do my best if I can help with debugging, but don't know where to start with this.

Crash reports, logs, images, videos

that would be an xkb bug I'd say

[coffebar]

xkb is part of xorg, isn't it?
What part does it take in it?

[vaxerski]

it's a part of xorg but it works and as such we still use it in wayland. It handles your keyboard layouts. It's a hunk of code for "human" stuff which nobody wants to rewrite cuz it works and is horribly complicated...

Generally I ask xkb for the layout and return whatever it says:

Hyprland/src/devices/IKeyboard.cpp

Lines 99 to 116 in ec092bd

	std::string IKeyboard::getActiveLayout() {
	const auto WLRKB = wlr();
	const auto KEYMAP = WLRKB->keymap;
	const auto STATE = WLRKB->xkb_state;
	const auto LAYOUTSNUM = xkb_keymap_num_layouts(KEYMAP);
	for (uint32_t i = 0; i < LAYOUTSNUM; ++i) {
	if (xkb_state_layout_index_is_active(STATE, i, XKB_STATE_LAYOUT_EFFECTIVE)) {
	const auto LAYOUTNAME = xkb_keymap_layout_get_name(KEYMAP, i);
	if (LAYOUTNAME)
	return std::string(LAYOUTNAME);
	return "error";
	}
	}
	return "none";
	}
