I started doing it and then it occurred to me that corfu is not needed
to trigger the issue. It is enough to do 'emacs -Q', 'C-x 5 2' and
switch between the frames, I did it by clicking with the mouse pointer.
I'm not familiar with Emacs internals, but does this observation fit to
Po Lu's message where he said:
I think menu bar updates are not double buffered on MS Windows, and as
a consequence flickers as Emacs removes the items to update them.
? I'll file a bug report.
Best, Arash
