I know you are wanting to explore Gimp 3 but since you are using Cannon stuff why not stick with Digital Photo Professional.
..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.
