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: freedesk...@lanrules.de
Hardware: x86-64 (AMD64)
Status: NEW
Version: 9.2
Component: Drivers/Gallium/r600

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:

Running on a Gallium 0.4 on AMD CAICOS from X.Org
OpenGL version 3.0 Mesa 9.2.0 is supported

GL feature data (useful? idk):
GL_ARB_texture_float: OK
GL_ARB_texture_buffer_object: OK [MISSING]
GL_ARB_texture_buffer_object_rgb32: MISSING
