In the sub-pixel case, our issue is that we pixel snap prior to applying transforms. When we have transforms that aren't integer translates, we shouldn't pixel snap, since ultimately we won't be aligning to pixels anyways. Removing the call to pixel snap in paintFillLayerExtended causes us to pass this test with sub-pixel enabled.

I'll diagnose the integral case as well.
