It's nice to see you contributing in the community again especially since you wrote a lot of the code for the Wayland backend.

Unfortunately this fix seems incorrect.

monitor->node->modes is set to modes as a realloc:

	monitor->node->modes = modes;

	if (flags & WL_OUTPUT_MODE_CURRENT) {
		monitor->mode = mode;
	}

	RGFW_FREE(modes);

It is monitor->node->modes that needs to be freed when the monitor is freed.

I knew that was a naive fix. I was trying to search the other uses of it
