Are you sure it looks exactly like that, and not more like a swimmy distorted look? If so then that's proper screen tearing in which case it's definitely a problem with your specific unit and you need to contact support to get a replacement or to troubleshoot on what the issue is. 

If you're using Quest with Link, that's in beta and not at all guaranteed to work properly. Contact Oculus Support and give them feedback, this might be a known issue or not and they might work on a software update to fix it.
