Idle() refers to sub_win.  However, you register it BEFORE sub_win
has been created.  That's dangerous because GLUT might call Idle()
before glutCreateSubWindow has been called.

I doubt that this is THE problem - but it's certain that it is a problem.

More likely (since you are clearly using threading) is that you have
some kind of race condition in some of the code that you aren't showing
us.  Different timing in the Linux and Windows versions would inevitably
occur - so any race condition might appear to work in one OS and not in
the other.

But it's really hard to say.
