Is this a phenomenon common to ND filters, or just the internal ones on the
XH-A1?

Internal filters actually do indeed affect the back-focus of the lens,
because they increase the length of the optical path. This will usually
only be visible on wide angles, and when trying to focus on infinity, turns
out your image gets blurry. So either zoom in a bit, or use external
ND-filters or a higher shutter-speed.
