This is a bug in ssvncviewer that I will fix in the next release (1.0.26)

It has to do with the (silly, IMHO) TightVNC security type rfbSecTypeTight
(that has nothing to do with security or encryption; it is used to enable
other features!)

I believe a workaround for you will be:

    ssvncviewer -listen -rfbversion 3.7

this reverts to the previous protocol version where there is no issue.
