On screen wakeup CVDisplayLinkCreateWithActiveCGDisplays is failing because Active display list is still empty and we never create a displayLink and content to MTLLayer are never updated. By adding 5 retries with 1 second gap after screen wakeup we are making sure that we are able to create displayLink for all active displays.
