I think I understand. The problem is that at maximum zoom the grid shows 10
mill, not 1 mill, which makes it very difficult to actually move the cursor
to a particular spot.

Perhaps it might be useful to flash a warning if somebody tries to set the
grid to less than 10 mill in eeSchema, in order to avert this sort of
problem.

It should be obvious from your attached images that the wires do not end at
the exact same coordinate as the pin connection coordinate.  That's why you
still see the unconnected indicators.  Both of these coordinates must be
identical for a connection to be made.  When the grid is set to 1mil, it
makes doing this really difficult.  If you use anything but a
50 mil grid to place symbols and/or draw wire and/or bus connections, you
are playing with fire.  Eeschema has always worked this way.  During
V6 development, connection snapping will be implement to resolve this issue.
