There is a problem on some runs under Windows, which until now have caused me problems to pass them because they are the only ones that work very slow, even supertuxkart crashes while trying to play them for some time.
The tracks are:

[list=]Zen Garden
Hacienda
Blackhill Mansion[/list]

Consequently not working grand prix circuits that carry this tracks such as:

To the moon and back
Outside the usual circuit

Note: In the Grand Prix only previously described tracks fail but the rest of the grand prix tracks work

its happen to me, user of windows ( about some track not working with normal )
in my case i solved the problem with change size of texture, there you can find in these 3 track that is "pix.png" or texture is same else with size = 1px and alpha/png
you just need to change it into size 10px or higher than that + keep as .png. even i try it that these track is working normally in my windows

if my advice is not work for solved your problem about track, i'm sorry

btw good luck, betharatux1

First make sure you have the latest driver installed for your system. And then resize them to have a power of two, 2x2, 16x16 or so.

Thank you all for your answers, well in my case this was a problem caused by the vertical sync and framebuffer objects.
Although the first is not enabled by default in supertuxkart. I had those options enabled.
Now I get to check those options I see in my case caused these tracks fail
So I disabled those two and solved all
