I believe that all the GOG-released games on Magic Carpet engine (including DK) are basically unplayable in high res. But yeah, I completely stopped giving GOG any attention after I bought Fantasy General on release and it had exactly the same instascrolling issue that was there when you tried to run it on your own. What's the point, seriously, people are willing to pay for it to get their games in a playable state, not to see the exact same thing you get when you run abandonware in dosbox.
For Fantasy General, reduce your CPU cycles to 15000 or 20000 (depending on your machine) and the instascrolling issue is gone.
