I think either you are misremembering, or you changed a setting for the library renders. With default settings in LDView, the bug would not affect renders of parts, since their geometry gets flattened in a way that masks the Mesa bug. The same does not happen for models. (Due to the geometric complexity involved, this is not an option for models.) See here:
