Well, my code which sets the font is in after-focus-change-function and
also in window-size-change-functions, and I could avoid the problem, in
a sense, by replacing that code with just customising the default face.

Thank you for working on this.  I dropped my local revert of 1b2511f and
applied your patch, but unfortunately the problem then reoccurs.

Happy to do more testing etc. -- let me know.

In my case I have the code in window-size-change-functions precisely
because I want some frames of a particular size to use a different font.
