If “Zoom to fit cross-probed items” is checked when selecting a component on schematic the pcb view is zoomed “out”, that’s not really useful, especially if you have a small component (0402 or smaller) and the pcb is big.
I noticed that the datasheet URL is carried as a field into the PCB footprint in v8. There seems to be a bounding area that encompasses all the hidden fields area around that footprint. If you remove the datahsheet url from the footprint fields then that would fix it. I don’t normally want the datasheet URL within the PCB fields area, some might, but if you remove it from the footprint, it would return back to how it was back in v7.
