Bug#844796:
Adding /usr/lib/x86_64-linux-gnu/mutter to /etc/ld.so.conf.d/x86_64-linux-gnu.conf and running ldconfig fixed it for me. ldconfig doesn't process directories recursively and the mutter directory was missing. Here's what the conf looked like before the edit. # Multiarch support
Bug#349700: Same problem here.
