Johnathan Thurston and Matt Bowen, North Queensland's best two on the night, scored tries two minutes apart - Bowen's a long-range effort involving his five-eighth and centre Brent Tate.
By the time Vidot rejoined the fray with 16 minutes remaining, the Dragons were down by eight and the Cowboys had a spring in their step.
It spoiled a tremendous red and white recovery after the Cowboys had scampered from the gates to lead 12-0 after 15 minutes and 18-6 before the half hour.
They seemed in the mood to rack up a big total but with the Dragons befitting from a string of penalties, the tide turned and Mitch Rein and Vidot scored before the break - the latter's coming off a superb Jamie Soward long ball.
When Dan Hunt crashed over five minutes after the restart, the Dragons had the momentum before Vidot handed it back.
