Re: Black bars when windows spawn
Hmm... can't reproduce on my machine.
However, looking at your screenshot, I can't help but notice the fonts you're using look very different from the Windows default? I would guess that might be the issue, though I am not really sure why a different font would introduce such an issue or how to work around it.

"The Athenians, however, represent the unity of these opposites; in them, mind or spirit has emerged from the Theban subjectivity without losing itself in the Spartan objectivity of ethical life. With the Athenians, the rights of the State and of the individual found as perfect a union as was possible at all at the level of the Greek spirit." -- Hegel's philosophy of Mind

Can't reproduce either but it's probably just a first-paint issue related to theme or theme overrides. That can sometimes happen (e.g. if there are many CSS rules to be processed on XUL windows and they involve required repaints of the window) if the widow is painted before all styling is fully processed (drawback of having startup be done as fast as possible).
You may be able to work around this by tweaking nglayout.initialpaint.delay

Do you have hardware acceleration enabled?
I see this on a old/slow machine when having
user_pref("layers.acceleration.enabled", true); in prefs.js.
