Yes, it looks correct (according to the feature of the X server, which
treats multiple monitors as a big, single monitor):

(display-monitor-attributes-list)
(((geometry 0 0 5760 2160) (workarea 0 0 5760 2160) (mm-size 1016 381)
(frames #<frame emacs@LAPTOP-0TO7HGG8 0x1132c30>) (source . "Gdk")))

I have also tried disabling RandR extension of the X server, but
nothing changed.

Additionally, I noticed that the *shape* of the mouse cursor changes
correctly in accordance with the contents of the window frame at the
mouse position; however, no click is recognized *except for* some
"shallow" part of the menu.
