Hi Alexander, Could you try either putting the mutex in the global scope or creating a small initializer class that calls getDefaultFont() that gets constructed in the global scope, the OSG has a helper macro for this so you could use:
OSG_INIT_SINGLETON_PROXY(InitDefaultFont, getDefaultFont()) Robert.
