You can :ref:`build <host_linux_on_linux>` a version of the host for Linux as

.. _gnome_wayland_decorations:
Why is there no title bar? / Why can't I resize the window?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This happens on GNOME Wayland because GNOME doesn't support the `standard
protocol`_ for server-side decorations. As a result, the window decorations
do not appear.
The easy solution is to use `libdecor`_. This is currently not packaged in
most distros, so you will need to build it from the linked git repository.
Once you have built it, you can then build the the client with libdecor
support by passing ``-DENABLE_LIBDECOR=ON`` to ``cmake``.
Please be aware that libdecor comes with overheads, which is why it is not
used by default. You should avoid it if possible.
An alternative solution is to hold down the Super key (Windows key on most
keyboards), and then right click on the window. This should bring up a menu,
which will allow you to move the window and resize it.
