in that thread they post many fixes. it happens with alot of sdl games.
not all of the fixes work for everyone. personally, the one below worked for me
Quote:Try creating a file in your home directory called .alsoftrc and add the contents drivers = oss.
1. Applications->Accessories->Text Editor
2. type drivers = oss in the test editor
3. save the file in your home directory ( /home/yourusername ) as .alsoftrc
fixed my issues with vdrift, supertuxkart, etc
