Chocobo Race(mini)game

[Melfice]

In Final Fantasy X, when in the Calm Lands, you can race some chick there to win some prize you need for Tidus' celestial weapon.
When racing I sometimes get hit when I get above the 10 balloons. Now that doesn't get me, because I understand the game adapts to your level. But what really ticks me off, is when the game says I get hit, but when I can clearly see I haven't.
Now my question is:

Are there more who have this problem/bug, or do I need glasses or lenses?
