I have odd behaviour since this update in xrLocateHandJointsEXT:

When controller is active since start of application, xrLocateHandJointsEXT returns isActive=true, locationFlags has XR_SPACE_LOCATION_POSITION_VALID_BIT but values appear to not be initialized.

 

Repro code:

std::optional<std::array<xr::hand_tracker::joint, XR_HAND_JOINT_COUNT_EXT>> xr::hand_tracker::locate(XrSpace space, XrTime time)
{
	if (!id || !xrLocateHandJointsEXT)
		return std::nullopt;

	XrHandJointsLocateInfoEXT info{
	        .type = XR_TYPE_HAND_JOINTS_LOCATE_INFO_EXT,
	        .next = nullptr,
	        .baseSpace = space,
	        .time = time,
	};

	std::array<XrHandJointLocationEXT, XR_HAND_JOINT_COUNT_EXT> joints_pos;
	std::array<XrHandJointVelocityEXT, XR_HAND_JOINT_COUNT_EXT> joints_vel;

	XrHandJointVelocitiesEXT velocities{
	        .type = XR_TYPE_HAND_JOINT_VELOCITIES_EXT,
	        .next = nullptr,
	        .jointCount = joints_vel.size(),
	        .jointVelocities = joints_vel.data(),
	};

	XrHandJointLocationsEXT locations{
	        .type = XR_TYPE_HAND_JOINT_LOCATIONS_EXT,
	        .next = &velocities,
	        .jointCount = joints_pos.size(),
	        .jointLocations = joints_pos.data(),
	};

	CHECK_XR(xrLocateHandJointsEXT(id, &info, &locations));

	if (!locations.isActive)
		return std::nullopt;

	std::array<xr::hand_tracker::joint, XR_HAND_JOINT_COUNT_EXT> joints;
	for (int i = 0; i < XR_HAND_JOINT_COUNT_EXT; i++)
	{
		joints[i] = {joints_pos[i], joints_vel[i]};

		if (not (joints_pos[i].locationFlags & XR_SPACE_LOCATION_POSITION_VALID_BIT))
			spdlog::warn("isActive but joints_pos[{}] position invalid", i);
		else
		{
			if (std::isnan(joints_pos[i].pose.position.x))
				spdlog::warn("joints_pos[{}].x is nan", i);
			if (std::isnan(joints_pos[i].pose.position.y))
				spdlog::warn("joints_pos[{}].y is nan", i);
			if (std::isnan(joints_pos[i].pose.position.z))
				spdlog::warn("joints_pos[{}].z is nan", i);
		}
		if (not (joints_pos[i].locationFlags & XR_SPACE_LOCATION_ORIENTATION_VALID_BIT))
			spdlog::warn("isActive but joints_pos[{}] orientation invalid", i);
		else
		{
			if (std::isnan(joints_pos[i].pose.orientation.x))
				spdlog::warn("joints_pos[{}].orientation.x is nan", i);
			if (std::isnan(joints_pos[i].pose.orientation.z))
				spdlog::warn("joints_pos[{}].orientation.z is nan", i);
			if (std::isnan(joints_pos[i].pose.orientation.y))
				spdlog::warn("joints_pos[{}].orientation.y is nan", i);
			if (std::isnan(joints_pos[i].pose.orientation.w))
				spdlog::warn("joints_pos[{}].orientation.w is nan", i);
		}
	}

	return joints;
}
