currently the Buffer can only grow. This increases Qemu memory footprint

But also after a VNC session has terminated there is one persistent buffer

getting smaller again.
Do you have any idea what caused the buffer to increase to 100MB in size
in the first place ? I would expect a full screen update would cause the
biggest buffer usage, and even for a 1920x1140 screen that should not
be anywhere near 100MB in size. IOW, i'm wondering if the 100MB usage
is symptomatic of a more serious bug somewhere else in the VNC code
that you're just masking you reducing buffer size afterwards.
