the problem should be on these lines: https://github.com/millermedeiros/swffit/blob/master/swffit/src/swffit_source.js#L191-193
this should fix it (didn't tested it since don't have IE9 and requires swfobject 2.2+):
//fix window innerSize difference when scrollbar is visible
var fixScroll = (!IE || (IE && swfobject.ua.pv >= 9));
iw -= (fixScroll && ih <= _mh)? 18 : 0;
ih -= (fixScroll && iw <= _mw)? 18 : 0;
my plan was to make a complete re-write of swffit but this plan is being delayed for the past 2 years.. not sure if I will ever make it since I'm not even coding flash that much and/or using swffit.
