Guacamole and noVNC have no common roots, AFAIK. So, with a different
VNC-Software showing the same problems, I decided to re-open this bug,
though I have no proof that it is really a Guix-Problem. At least
people who want to install Guix would be annoyed and might run away. As
Robert said, he didn't experience this with any other Distro, that could
be a hint we are doing something wrong here.

I guess you (Ludovic) have tried the installer with QEMU and its
VNC-Server, maybe even with different VNC-clients?

We could try different setups in that directions.

We could look extensively at the code with the mode switches and compare
it with specs about mode-switching? Until now, I have no knowledge in
that area.
