What did you upgrade? Please look at /var/log/apt/*.log*. gnome-shell hasn't been updated in sid since April, so unless your sid installation was previously extremely outdated, it wasn't a gnome-shell upgrade that triggered this. After upgrading whatever packages triggered this, did you reboot, or log out and back in, or neither? If you didn't do either, the old gnome-shell will have continued to run with the old libraries, in which case we'd need to know which gnome-shell version and relevant libraries (clutter, mutter, gtk, gdk-pixbuf) were installed at the time you started the VNC session. Are there any relevant messages in syslog, the systemd Journal, ~/.cache/gdm/session.log (if you use gdm), or ~/.xsession-errors? (Also, in future please use reportbug, which would have listed all the relevant packages after your upgrade already.)
