Black Screen between videos

Meeting SDK
1

Description
I noticed that when I try to pin videos using PinUserVideoToFirstView(userID) function I always get black screen between videos. Is there a way to get rid of this black screen ?

Which Desktop Meeting SDK version?
DeskTop Windows SDK v5.7.1.644

To Reproduce(If applicable)
Steps to reproduce the behavior:
if (count_participants > 3)
{
for (int i = m_currentPinUserId; i < count_participants; i++)
{
unsigned int user_id = participants->GetItem(i);
ZOOM_SDK_NAMESPACE::IUserInfo* user_info = participantsCtlr->GetUserByUserID(user_id);

		if (this->CanSpotlightOrPin(user_id))
		{

// videoCtrl->UnPinAllVideosFromFirstView();

			videoCtrl->UnPinVideoFromFirstView(last_user_id);

			if (videoCtrl->PinVideoToFirstView(user_id) == ZOOM_SDK_NAMESPACE::SDKERR_SUCCESS)
				{
					m_currentPinUserId = i;
					last_user_id = user_id;
					// done
					status = true;
					break;
				}
		}
	}
}
