I have added two screenshots, the first is before hitting F5/opening inventory and the second is after. It persists until I open my inventory or hit F5 while outside of the minecart or other vehicle.
For me, it only happens if I open my inventory or F5 while riding any sort of vehicle, or in SMP when other players near me are in minecarts.
