VNC display issue with OUI

The above screenshot might look familiar to some people. This happens when we use RealVNC's default windowing manager twm. This is specified in the hidden directory .vnc which has a file called xstartup:

# cd $HOME/.vnc
# cat xstartup
#!/bin/sh

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &

You should comment the line twm & and add a new line. Final contents of xstartup will look like this:

oralmpd1@tsgsd1005 # oralmpd1@tsgsd1005 # cat xstartup
#!/bin/sh

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
/usr/dt/bin/dtconfig &

Once you use the Solaris dtconfig as windowing manager, this problem doesn't occur. When you start vnc with the default windowin manager for Solaris.
