Summary 06494: thndrbld, thndrbld1, thndrbldd: Objects momentarily disappear
Description At certain times during the demo and gameplay, all of the objects on screen (buildings, trees, enemies, bullets, player's helicopter) will disappear for a single frame. This can be easily observed at 35 seconds into the game's demo mode. In a 5 second span there are 4 times when all of the objects disappear for a single frame, leaving only the background. Possibly not a bug with MAME but with the original hardware.
Steps To Reproduce
Additional Information If the SUBCPU is underclocked to 90%, the problem becomes more severe. If overclocked to 110%, the problem is resolved.

I'll confirm this for now as I see the exact same thing as your snap shot when creating an AVI with MAME and cycling through it frame by frame with MPC-HC.
