I'm not quite sure what exactly you've got going on, but it sounds
like the right thing to do is patch the drywall. I've also used
various extruded polystyrene bits, and polyethylene closed cell foam
caulk backer pieces (typically cylinders of foam that you put in to
take up most of the space, sold for the purpose.) But fixing the
drywall to match the window seems like it's the best solution (might
cost too much, of course.). It's a whole lot easier to cut a few
inches more out and so you've three square sides, and just the
window's edge is uneven.
