What actually is the difference in style between your two screenshots?

Can you provide a minimal code example that exhibits this issue? If I freeze a basic wxWidgets hello world app, the window and its title bar look look the same as in the original unfrozen script... So there might be other factors at play, but to single them out, we need a common reproducer to test with.
