Any idea how recent is "recently"?

You visit a file that is not already visited in some buffer in the
current Emacs session?

Does it happen only immediately after visiting a file, i.e. upon what
should have been the initial display of the file you visited?  Or does
it happen in other situations as well?  If this happens only upon
visiting an unvisited file, does it happen every time you visit such a
file?

Do you have some features enabled that affect the initial display of a
visited file?  Like save-place or something else that invokes a hook
upon visiting?  Or some display-related feature that could be
relevant?  If you do, what are those features/hooks?

Does it help to disable double buffering?

Do you see anything interesting in *Messages* after such an incident?
