The problem is that game opens a core context but expects to use legacy/compatibility extensions like GL_ARB_multitexture. Same happens with GL_ARB_texture_compression and GL_ARB_vertex_buffer_object which it queries as well. You can get a bit further by forcing a legacy context (using MESA_GL_VERSION_OVERRIDE=2.0) but then after getting through extension checks there are problems with shader compiler because shaders seem to be gles3 (have "#version 300 es" in them), I'm not sure how to debug this further, I think there are issues either in the game or glew.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
