In Temple of Doom of Indy 2, one of the vehicles you can use in a race is a tractor. Depending on how the game runs, the tractor might move in a jerky, bouncing way. That might seem normal (it is a tractor, after all), but it's actually a bug. This makes the race an almost impossible challenge.

The issue can be fixed by changing the resolution. At 800x600, the tractor moves normally and the race becomes no more difficult than any other.
