I don't think the updated docking computer fix is in this current version 2.3.10 Last I heard they are still working on it and is aware of the problem. I really hope they patch and fix the DC promptly.
We'll see. The problem with the DC is the edge cases and they are difficult to set up reliably and repeatably for testing.
By edge cases I mean things like the transitions between outside the dock to through the slot to inside the station to descending onto the pad. Each of these is handled slightly differently and if you enable the DC just a the transition stage you can get unpredictable result.
This also includes things like engaging the DC just outside the slot from an angle of more than 45 degrees off the centre line with a large sideways component to your approach vector.
The other thing to remember is that it is
not an auto pilot. It is for docking so the best way to make it work properly is to manually line the ship up and when flying straight to the slot, or pad in the case of outposts of planetary stations, then let the DC take over.
