I was hitting this on disco-proposed. I found that it was resolved by setting an APT priority of -1 for disco-proposed and doing a dist- upgrade (i.e. downgrading all packages to disco-updates). I found that downgrading mutter and gnome-shell was insufficient (I guess there are lots of related libraries).
