Description of problem: GL_EXT_texture_compression_s3tc doesn't appear to be supported by mesa/gallium for my card (Mobility Radeon HD 5430 CEDAR) even though the hardware should support it fine. Some earlier versions of mesa apparently did support it (see http://feedback.wildfiregames.com/report/opengl/device/Gallium%200.4%20on%20AMD%20CEDAR for example) Version-Release number of selected component (if applicable): mesa-libglapi-8.0.3-1.fc17.x86_64 mesa-dri-drivers-8.0.3-1.fc17.x86_64 mesa-libGL-8.0.3-1.fc17.x86_64 How reproducible: Every time Steps to Reproduce: 1. Have a Mobility Radeon HD 5430 card 2. Attempt to run software which needs GL_EXT_texture_compression_s3tc (such as Psychonauts from the Humble Bundle V) 3. Watch software fail to run thinking required GL extension is not available. Actual results: Psychonauts segfaults ( ... ERROR: Missing required OpenGL extensions: - GL_EXT_texture_compression_s3tc Start Up completed in 0.27 seconds Segmentation fault ) Expected results: I get to play my game Additional info: Gallium 0.4 on AMD CEDAR 02:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5430 Series]
