Dear Jochen - I have encountered this problem also, but only on certain machines, and I have yet to find a satisfactory way to resolve it.
I don't have a fix, exactly, but if you place the linked python script (https://www.dropbox.com/s/h84q68yofwmito6/wherami.py) in your ~/.coot-preferences directory it will do two things which may help: 1. Turn off labeling atoms on recenter. 2. Give you a new toolbar button, "Sequence context", which when pressed will give you the residue name, number and local sequence context of the centered residue as an info dialog (partially replacing the functionality of atom labelling). The file (https://www.dropbox.com/s/0b4bebwxw0p9x0e/oli_custom.py) has a more extensive array of tweaks, including this one. Hope that helps, Oliver.
