Graph view and local graphs display is broken

The graph view is not displaying correctly all of a sudden; I was just entering text and when I opened the graph view, it appeared broken. See image below.
I tried deleting the Application support library, nothing changed.
The same happens with every one of my Vaults, irrespective of theme, plugins, etc.
0.14.6 on an old (2009!) iMac, macOS 10.12.6. Never had an issue before with this configuration.

Update: Could this error in the console be related?
