  Message : Change the component type of STENCIL_INDEX8 to UNSIGNED_NORMALIZED That way RenderbufferStorageMultisample accepts STENCIL_INDEX8 as an internal format for a multisampled buffer (samples > 0) as it isn't concerned by the restriction on integer component types anymore. This is consistent with the component type returned by the NVIDIA driver.
