That's not relevant: 619194 is a buffer position, whereas -14 is the y-coordinate (in pixels) passed by posn-at-point to posn-at-x-y. The latter cannot cope with negative y coordinates, for reasons that should be obvious. The question is how that -14 coordinate came into existence. If you can step with a debugger into Fpos_visible_in_window_p, and see what's going on there, that would be helpful. (I cannot try that myself, as my systems don't support pdf-view-mode.) Thanks.
