wrong colours with a 16 depth

[Frederic Dumas]

Hello,

I am running vnc server from a linuc pc with:
vncserver -depth 16 -geometry 1280x1024 

When the viewer is set with a 16 depth, I do not get all the colours
right. It only works well with a 24 depth, which is slower and weird, as
the server only uses a 16 depth. I have tried to play with the command
options and did not succeed in having a 16 depth with all colours. I
have tried to follow FAQ suggestions with no result. Does anyone have a
hint on this problem?

Thanks for any help,
Frederic

PS:
- I use the following versions:
vnc-3.3.3r1_unixsrc.tgz
vnc-3.3.3r1_x86_linux_2.0.tgz 

- I run the viewer on an sgi workstation (Irix 5.3). I have removed (!)
the usleep lines in the source as it is not known by Irix 5.3 (I do not
think it could be the problem?)

- 'vncviewer -truecolour -depth 24' gives the right colours and produces
the following output:
VNC authentication succeeded

- 'vncviewer -truecolour -depth 16' gives wrong colours and produces the
