Application Issues

+ +

+This page documents known issues with some OpenGL applications. +

+ + +

Topogun

+ +

+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 +for the 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 MESA_EXTENSION_MAX_YEAR 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 +

+export MESA_EXTENSION_MAX_YEAR=2001
+
+before running the game. +
