+<h1>Application Issues</h1>
+
+<p>
+This page documents known issues with some OpenGL applications.
+</p>
+
+
+<h2>Topogun</h2>
+
+<p>
+<a href="http://www.topogun.com/">Topogun</a> 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.
+</p>
+
+<p>
+Mesa 9.1.2 and later (will) support a DRI configuration option to work around
+this issue.
+Using the <a href="http://dri.freedesktop.org/wiki/DriConf">driconf</a> 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.
+</p>
+
+
+<h2>Old OpenGL games</h2>
+
+<p>
+Some old OpenGL games (approx. ten years or older) may crash during
+start-up because of an extension string buffer-overflow problem.
+</p>
+
+<p>
+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.
+</p>
+
+<p>
+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.
+</p>
+
+<p>
+For example, if the game was released in 2001, do
+<pre>
+export MESA_EXTENSION_MAX_YEAR=2001
+</pre>
+before running the game.
+</p>
