Yeah, still crashes with Glamor as of git 081a537.

That's the standalone glamor tree. I mean glamor from the current xserver Git tree.

Anyway, I think the attached backtrace can only happen if Steam uses GLX indirect rendering (current versions of Steam present a warning dialog on startup when that's the case). You can try starting Steam with LIBGL_DEBUG=verbose to see why it's not getting direct rendering.
