             Bug #: 47900
           Summary: Sampler does not work with cubemaps in 16-bit
                    component pixel format
    Classification: Unclassified
           Product: Mesa
           Version: 8.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: llyzs@163.com


If a cubemap is created using 16-bit component pixel format like
PIPE_FORMAT_R16G16B16A16_UNORM or PIPE_FORMAT_R16G16B16A16_FLOAT, it will not
be sampled correctly in fragment shader and generate garbage output. Those
16-bit formats works just fine when using in 2D texture, and the cubemap using
8-bit format also works. It's just the combination cubemap+16bit that does not
work.

Any hints?

EDIT: Only PIPE_FORMAT_R16G16B16A16_FLOAT does not work. 16-bit integer types
work.
