Had this exact problem on Gutsy, Hardy, and now Intrepid, using "xvncviewer -ZlibLevel 7 [vnc_display]".

Most of the VNC displays I'm connecting to are Windows 2003 running on Xen (SuSE Linux Enterprise Server 10 SP2). The display sizes range from 640x480 to 800x600. I typically access them through SSH port forwarding, but that may be irrelevant.

Anyway, long story short, I moved over to xtightvncviewer (based on the post I found at http://ubuntuforums.org/showthread.php?t=695273 ). The problem completely went away, but the speed of the session was abysmally slow (VNC Displays are at a remote data center, accessed through a VPN tunnel). It turned out I needed to specify the encodings. The command that I'm running now is:
xtightvncviewer -compresslevel 7 -encodings "copyrect tight hextile zlib corre rre raw"
I just put that in my .bash_aliases as the command 'vnc'. So all I need to type is 'vnc [vnc_display]'.

Works like a charm.
