graphic

this graphic variable is a GUI class right? If so than you are doing something you should never do in Qt: using GUI classes in other threads! GUI classes should only be used in main thread.
If you want to trigger an UI change from other threads then just emit a signal there and connect a slot in your main thread where you then update the UI.
