In fact, it seems partially recognized. I find the situation with
split windows (C-x 3) even weirder - too weird that I cannot explain
in text, so forgive me for the Dropbox link to a ~100 MB movie (with
sounds of the mouse button up and down - sorry for my unstable left
hand!):

As you can see, the behavior of mouse clicks on the right split window
seems almost random. The environment is:
- My left 1920x1080 monitor is

- My right 3840x2160 monitor is
https://www.dropbox.com/s/2advpxq1988uxac/IMG_6259.JPG?dl=0
- The border between the split windows of Emacs is slightly to the
right of the center of the right monitor.
- The X server treats the two monitors like a single 5760x2160 monitor.
- Given that, there seems nothing wrong with the output of xdpyinfo
and (display-monitor-attributes-list).
- There also seems nothing wrong with other X clients or GTK applications.
An additional (perhaps important) observation is:
- The problem occurs only when the right display is added after the X
server (and its first X client - mlterm in my case) started.

The code is fine, but I just cannot carry the 60-inch monitor with me
to other places (lecture halls, meeting rooms, cafe, home, etc.) and
have to find time:-) to sit in my office to investigate this (but I
will continue to look into what's happening)!:-)
