           Summary: Framebuffer Depth textures (Shadow mapping) - FBO-EXT
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: s3734770 at mail.zih.tu-dresden.de

I'm running a depth map demo that uses fbo depth maps as a render target. The
fbo (EXT) is filled with static stuff (like a mask that is moved over the
screen). So the contents i drawed into the buffer (the depth component is bound
to the buffer) are ignored

I don't know if this feature is in progress or if you know what is missing in
the driver.
If you have no clue, I can offer the following things after a request:
 - Pics of the artifacts
 - Videos that show that the depth texture is not updated
 - Explanation how i set up the FBO/Renderbuffer

The thing works with fglrx.

Extensions I used:
Renderbuffer_EXT (for depth store)
