          Priority: medium
            Bug ID: 69689
          Assignee: dri-devel@lists.freedesktop.org
           Summary: FBO with GL_RGBA16F texture format silent drawing
                    corruption
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: freedesktop@lanrules.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 9.2
         Component: Drivers/Gallium/r600
           Product: Mesa

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
