The patch fixes compiler warning that there is too many ALU instructions and
textures are visible. Unfortunatelly it corrupt lights in this game.Also
similar corruption you can see on screenshot "fishblow" from webgl test
http://ie.microsoft.com/testdrive/Performance/FishBowl/

And in supertuxkart shining parts of some vehicles have also similar
corruption.
