In this particular case, GL_APPLE_texture_max_level is an OpenGL ES 1.x and 2.x extension. I suspect the version of glxinfo you're using only shows desktop OpenGL information, so it makes sense that it doesn't show the ES extension. It is confusing that Mesa gives an error message for disabling a extension that doesn't exist in the current API. The code could be smarter about that.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
