<pre>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</pre>
