what is this mysterious milky-white cloudy-like white-smoky air-fumes coming out constantly from the combat aircraft flying seemingly a close-air-suport combat air patrol mission in very high region of the sky in the vast aerial frontier of the airspace of the beloved homeland of our IsLamic republic of PakisTan ... ?
These are vortices, that being low pressure have a lower temperature, causing condensation of water vapors and thus appearing as "milky-white cloudy-like white smoky air-fumes" as you so eloquently put it.
These vortices are a good thing and a mark of good design. JF-17 has them as well. That is why it always appears as though it is wearing a 'dopatta' - looking like a deadly baji.
Being an aeronautical engineer, @Munir can tell you more about it.
