It is a regression from Emacs 26.? with the following commit:

    Minor redisplay optimisations
    * src/frame.c (Ficonify_frame): No need to redisplay everything.

The following patch fixed it:

    Notify when a frame is iconified in Lucid builds
    If Emacs is built without x toolkit or built with Lucid,
    then we have to notify when a frame is iconified (Bug#42655).
    - src/frame (iconify-frame):
    Set windows_or_buffers_changed to a non-zero value.
