..sorry.. linux user here, no idea about Picture Window 8
File size ? have you checked the bit depth ? 8 / 16 / 32 and encoding linear / non-linear
Hopefully a Gimp dev will come along and examine the issue.

Your comment about encoding may be actually pointing in the right direction - since the TIFFs produced by GIMP are exactly 2x bigger than standard 16-bit TIFFs.
I am getting some questions from the GIMP team, and also I am providing more data and info - including the TIFFs in question.
Hopefully all will be explained and/or fixed.
