Dear Maintainer, * What led up to the situation?

It seems that a new libvncserver patch in debian/patches/0003-rfb-increase-update-buf-size.patch create an ABI incompatibility between x11vnc and libvncserver.
Could you try this: rebuild x11vnc 0.9.16-7 (as found in Debian bullseye, if it's bullseye that you use) from source with the latest libvncserver version (library + dev:pkg) installed?
With the rebuilt x11vnc, does the error persist? Or is it gone, then?
