I don't know what you're using for Mod4, but X doesn't intercept any
two-key bindings on its own. Some three-key, but no two-key.
Occasionally the platform firmware will intercept some combinations,
but typically that doesn't affect cursor visibility (instead it's more
like "change display configuration" or "increase brightness"), so I
would expect this is a function of your desktop environment.
