39312e4b - Vision framework GUI fix: when changing a synthesizer don't keep settingsInstance alive (PR #10519)

Vision framework GUI fix: when changing a synthesizer don't keep settingsInstance alive (PR #10519) * GUI bindings were holding onto a reference to settingsStorage and not allowing the settingsInstance to object to die. * Use a weakref.proxy instead. * Refresh GUI when reference to driver dies.
