            Bug ID: 79431
          Assignee: dri-devel at lists.freedesktop.org
           Summary: OpenGL OpenCL interop results in corrupted
                    renderbuffer object image
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: pavol at klacansky.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

I use APP SDK with OpenCL running on CPU and r600 driver on GPU (AMD Mobility
3650) to compute image. If I use OpenCL image, I get correct result, however if
I want to display image using OpenGL (interop), it is corrupted.

I create renderbuffer object, than link it with OpenCL
(clCreateFromGLRenderbuffer) and then after image was computed I blit it
to back buffer.

I tested it in lab on nVidia proprietary driver and it works well, I suspect
the problem is in renderbuffer sharing.

OpenCL is 1.2, OpenGL 3.3.
