Sorry, actually it works, I missed the logged messages because the conten= t of the *Messages* buffer is not refreshed to show new logged messages from the calls of the window-scroll-functions hook such as (add-to-list 'window-scroll-functions (lambda (window display-start) (message "window-scroll-functions %S %S %S" window (window-buffer window) display-start))) This means that C-l (recenter-top-bottom) doesn't redisplay the frame - which is strange since it calls 'recenter' with non-nil arg REDISPLAY. Only after switching to the *Messages* buffer with 'C-x o' it gets redisplayed and all previously emitted messages appear in it.
