          Assignee: idr at freedesktop.org
           Summary: GLSL: derivatives in ES3 wrongly require
                    OES_standard_derivatives to be enabled

          Severity: normal
    Classification: Unclassified
                OS: All

          Hardware: All

OpenGL ES 3.0 shaders wrongly require OES_standard_derivatives to be enabled,
in order for dFdx and friends to be available. Looks like builtin_function.cpp,
fs_oes_derivatives has wrong logic; it should allow ES 300 without the
extension.
