Sometimes emacs seems to decide to recenter, when it has "too much" input while display is taking its time (which I guess it might for e.g. font-locked window.c or a bunch of foreign scripts on view-hello-file) I found the faster I set keyboard autorepeat the easier it is to make happen. e.g. with my usual "xset r rate 150 60" it happens very occasionally, but with "xset r rate 150 180" it happens a lot.
