Based on Personal Experience:
As Loose Connector:
My 13" 2017 MBP had this issue. Its screen replaced 11 times in hopes to fix the flickering. Having been so patient, I was finally gifted a new device from Apple. The reason why this was occurring - according to Apple - is that the connector to the LogicBoard from the screen kept becoming loose. So, get this worked on, as it may may be a loose connection.
