They are on some rocks in episode 1, on all level exits, but most apparent on the tree joints in episode 2. Upon startup this is printed: Mesa: User error: GL_INVALID_OPERATION in glUniform(program not linked) BTW is it normal that it almost always segfaults on startup? The backtrace is different each time (64 bit).
I forgot to add that the corruption only occurs, if the "use shaders" option is enabled in the game. It's not relevant anymore, because I tried with mesa 10.1, and this corruption is gone. Closing.
