Just downloaded the 0.7-alpha 2 of SuperTuxKart, and have noticed that no kart choices (except for random kart) are displayed after I have changed the resolution under options. The bottom bar on the kart selection screen (with "Standard", "Special" & "All" buttons) is also missing, and the model of Tux still displayed, even though there is no icon to select him. Clicking on the "Random Kart" button crashes the game. I am running Windows 7, and was able to successfully reproduce this bug three times. Here are some screenshots:
