Did you previously set the display scaling to 200% on the local
display? GNOME has a tendency to store and restore display settings in
a way that interferes with VNC servers. I will try to reproduce the issue.

I experience a possible bug regarding the Gnome display scaling (or
I'm just doing something in the wrong way).
To reproduce:
1. start server on remote host: /opt/TurboVNC/bin/vncserver -fg
2. setup ssh tunnel from local to remote: ssh -t -L
5900:localhost:5902 remoteserver 'read dummy'
3. connect a client from local machine: /opt/TurboVNC/bin/vncviewer
localhost:0
This results in a working session, with a Gnome session running.
In my case, it has the display scaling set to 200% (can be checked
with: gnome-control-center display)
4. I can toggle scaling to 100% and things look good.
Now, if I terminate the vncviewer session and reconnect, the scaling
is back to 200%.
Also, if I switch to fullscreen, the scaling is back at 200%. And if I
set it back to 100% in fullscreen, then toggle fullscreen off, the
scaling jumps back to 200%.
