Renaming glamor_priv->dispatch and wrapping the access to the dispatch table with a function that also ensured the context was bound. dispatch = glamor_get_dispatch(glamor_priv); ... glamor_put_dispatch(glamor_priv); So that we catch all places where we attempt to call into GL withouta context. As an optimisation we can then do glamor_get_context(); glamor_put_context() around the rendering entry points to reduce the frequency of having to restore the old context. (Along with allowing the context to be recursively acquired and making the old context part of the glamor_egl state.)
