Oh well, I forgot about that. The problem is that Gnome's Wayland
session does not provide server-side window decorations; instead, the
clients, e.g. mlterm, have to render the decorations themselves. This is
called client-side window decorations. There have been lots of
acrimonious discussions about this "feature" which you can read up on if
you are interested, but this will not change anytime soon (there are
other wayland compositors like sway that do have server-side
decorations) and mlterm does not provide any window decorations. I don't
know whether Araki Ken plans to implement this at some point.

I forgot about it because I don't use Gnome anymore. Unfortunately, it
probably renders my idea useless. Let's see what Araki Ken has to say
about this, but for now, here are some other ideas:

1. Does the mouse behave weirdly under Gnome's X11 session as well? You
can choose the X11 session when logging in. I think it is called "GNOME
Classic". This is a somewhat temporary solution, but X11 support will
probably not be dropped anytime soon.

2. mlterm can masquerade as a libvte terminal. libvte is the library
that is used by Gnome Terminal and many other terminal emulators
(termite, guake, ...). The way this works is that the libvte library
headers are replaced so that if you start e.g. a Gnome terminal, the
terminal will actually be an mlterm within the normal Gnome terminal
window. This could maybe solve your problem, but setting it up is a bit
involved and I never tried it.  You can find instructions on how to do
this in src/tip/gtk/README.
