            Bug ID: 95299
           Summary: [BDW, deqp] gles31 tests occasionally fail to create
                    compute shader
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965

          Reporter: mark.a.janes at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

This failure mode is not easy to reproduce, but it causes intermittent false
positives in the CI:
