a bug in windows aero.
this can happen when you switch from 60p to 23p. and you only have one desktop composition so if you use a TV at 23p and a monitor at 60p you get a composition rate of either 23p or 60p for both screens. only FSE and overlay mode don't need the desktop composition so they will work any way.
under windows 8+ a mismatch after changing the refreshrate shouldn't happen what so ever.
