This page documents known issues with some OpenGL applications.
Topogun for Linux (version 2, at least) creates a GLX visual without requesting a depth buffer. This causes bad rendering if the OpenGL driver happens to choose a visual without a depth buffer.
Mesa 9.1.2 and later (will) support a DRI configuration option to work around this issue. Using the driconf tool, set the "Create all visuals with a depth buffer" option before running Topogun. Then, all GLX visuals will be created with a depth buffer.
Old OpenGL games
Some old OpenGL games (approx. ten years or older) may crash during start-up because of an extension string buffer-overflow problem.
The problem is a modern OpenGL driver will return a very long string
glGetString(GL_EXTENSIONS) query and if the application
naively copies the string into a fixed-size buffer it can overflow the
buffer and crash the application.
The work-around is to set the
environment variable to the approximate release year of the game.
This will cause the
glGetString(GL_EXTENSIONS) query to only report
extensions older than the given year.
For example, if the game was released in 2001, do
before running the game.
