I create an FBO with internal texture format GL_RGBA16F. I also tried GL_RGBA32F. Both work fine with my nVidia GPU. With my ATI card it fails. - No error is reported when creating and binding the FBO. - Blitting the FBO on screen results in random patterns (first run), then black output System information: Caicos [Radeon HD 6450/7450/8450] Running on a Gallium 0.4 on AMD CAICOS from X.Org OpenGL version 3.0 Mesa 9.2.0 is supported Linux 3.10.10-1-ARCH kernel GL feature data (useful? idk): GL_ARB_texture_float: OK GL_ARB_texture_buffer_object: OK [MISSING] GL_ARB_texture_buffer_object_rgb32: MISSING
