Seeing as it is an old Windows XP application it's probably relying on GDI+ and it grabs the screen shot from the buffer there. After XP, everything went over to WDDM for the composting and I'm guessing there is still some sort of fall back and that's what your screen shot program is pulling from the buffer.
It's working from the outside in whereas IL-2's built in screen shot application probably pulls from the render pipeline itself so it's no big problem there even when IL-2 is ages old.
Probably too many guesses in there to make any real sense (apologies Windows software architects) but I can say with some certainty that the way that Windows renders stuff on screen made a big change from XP to Vista and both 7 and 8/8.1 still use the WDDM.
If they have an updated utility then that will probably be aware of the newer environment and should work. Otherwise your options are FRAPS or use the built in one - which, IMHO, works just fine these days.
