Using Views to List a Member's Organic Groups (7.x-2.3)
This is how to get the OG membership ID:s to start with.

Add new view.
Show -> OG membership (important!)
Then in some display add a contextual filter -> OG membership: Entity id.
Provide default value -> Type -> User ID from logged in user.
Override title: %1's groups.
Specify validation criteria -> User.

Now you have the list of ID:s.

Next to get the actual titles of the groups (as the base table is OG membership, not node), Add a relationship -> Group Node from OG membership.
Add a field -> Content: Title.
Relationship -> Group node from OG membership.

Now you have the titles too. Add some filters and sort criterias to taste.
