Well, after a new hard disk, re-install, rebuild, etc. I've had
another look and it seems that I'm still not correctly matching
the server and client pixel formats in FindBestVisual(). However,
there is a quick fix for 16-bit truecolour on Linux, start the
vnc viewer as follows:
vnc -trucolour -depth 16 <hostname:n>
where <hostname> is the name of the VNC server and <n> is the
display number. I've tried this with a 16-bit Xvnc server and
with nano-X running on a 16-bit Linux framebuffer, and the
colours look OK.
Note: this only works with the updated viewer from my web site.
For those who missed the earlier post, get:
