vorrei sapere se è possibile fare un refresh di un JFrame perchè si rovina

Se si "rovina" è perché magari non hai gestito il painting in modo corretto (se disegni su un "tuo" componente) o non hai rispettato le regole di threading di Swing o hai aggiunto dei componenti ad un container ma senza rivalidare il layout o altro.

Senza vedere il codice mi servirebbe la famosa sfera di cristallo per dirlo.
