--- Comment #5 from Rodney W. Grimes <rgrimes at FreeBSD.org> ---
Try using tightvnc, which iirc itself crashes in many situations due to rect
outside limits.  I think this is caused by what cem spotted in that we ignore
the viewer set size stuff, and tightvnc almost always sends a resize on startup
to match what ever the display window is, ignoring the window size sent by the
server, which probably leads to the rect outside limits error.

Our bhyve/vnc implementation is extremly finicky about how it works with
clients,
most fail infact when doing anything but very simple stuff.
