> So maybe there two bugs here?

We won't know until there's an example SVG file attached to allow further investigation (yes, I should have asked for it before adding my initial comments).

Note that the upper left corner of an image needs to be at an integer-value position (the other corners and the width/height values don't really matter if the bitmap image has the original size from importing). Any scaling of the bitmap image will additionally change the precision of its content (affected by the preference setting for oversampling of bitmaps).
If on the other hand the affected bitmap images had not been pasted or imported intentionally, see bug #675438 (comment #2).

There's also a known bug in PixelSnap (apparently transform attributes of a parent node (e.g. the layer group after resizing the page) are not correctly considered):
