As I said in the original post, correct rendering is resumed when I
click on a menu and I see that Emacs has in fact updated the buffers
according to my inputs.  Even before clicking on a menu item I see that
Emacs processes my input when for example menus change in response to
inputs: e.g., when I switch buffers, I see different menus at the top
according to the modes that are active in the respective buffers but the
windows are not updated.  So it seems that the problem really is
updating of the window displays.

I'm fairly sure that the problem was introduced by a recent change in
Emacs because I didn't change anything else at the time when the problem
first occurred.  Specifically, I did not change the window manager or
its configuration.
