            Bug ID: 98456
           Summary: [CTS, ES32, SKL] CTS "core" test suite causes
                    INVALIDE_OPERATION errors on skylake
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: kenneth at whitecape.org
          Reporter: mark.a.janes at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

When the ES32-CTS.core and ES31-CTS.core suites were enabled on Intel's Mesa
CI, failures in other parts of the test suite were seen on SKL.

For example:
ES32-CTS.functional.shaders.builtin_functions.common.abs.ivec2_mediump_geometry
Failed to set up framebuffer object: glGetError() returned GL_INVALID_OPERATION
at glsShaderExecUtil.cpp:638

ES32-CTS.functional.shaders.arrays_of_arrays.return.explicit.mat3_3x4_fragment
ShaderCase::execute(): start: glGetError() returned GL_INVALID_OPERATION at
glsShaderLibraryCase.cpp:946

ES32-CTS.functional.shaders.multisample_interpolation.interpolate_at_offset.at_sample_position.default_framebuffer
glGetError() returned GL_INVALID_OPERATION at
es31fMultisampleShaderRenderCase.cpp:475

Running the tests with process isolation removes the errors.

These tests are disabled in the CI pending resolution.
