[Vm-dev] macOS Window Bugs

Hi Ronie, hi all,

Now that I've fixed the fullscreen issues on macOS, I found another problem which I don't understand: I can't close the About panel for some reason. AFAICT this never worked with the new Metal backend. It appears that the window title bar is not initialized correctly, at least it doesn't respond to mouse event. Also, it looks like this is the same reason why the title bar buttons cannot be clicked once the fullscreen mode was triggered via the green fullscreen window button.

This seems like something super easy to fix, but I don't know much about macOS UI development. Any help would be appreciated!

Best, Fabio
