A challenge to doing more sophisticated (e.g. compressed) client-side

A drawback of the "-ncache n" method is that in the VNC Viewer you can

cannot be seen.

Another drawback of the scheme is that it is very memory intensive,

The reason for so much memory is because the pixel data is not

backing-store (the window's actual contents) and save-unders (the
pixels covered up by the window) are used for window caching that
introduces an additional factor of 2 in memory use.
The large memory consumption of the current implementation can be
thought of as a tradeoff to providing caching and being compatible
with all VNC viewers and also ease of implementing. Hopefully it can
be tuned to use less, or the VNC community will extend the protocol to
allow caching and replaying of compressed blobs of data.
Another option to experiment with is "[549]-ncache_cr". By specifying
it, x11vnc will try to do smooth opaque window moves instead of its
wireframe. This can give a very nice effect (note: on Unix the realvnc
viewer seems to be smoother than the tightvnc viewer), but can lead to
some painting problems, and can be jerky in some circumstances.
Surprisingly, for very slow connections, e.g. modem, the -ncache_cr
option can actually improve window drags. This is probably because no
pixel data (only CopyRect instructions) are sent when dragging a
window. Normally, the wireframe must be sent and this involves
compressing and sending the lines that give rise to the moving box
effect (note that real framebuffer data is sent to "erase" the white
lines of the box).
If you experience painting errors you can can tap the Alt_L key (Left
"Alt" key) 3 times in a row to signal x11vnc to refresh the screen to
all viewers. You may also need to iconify and then deiconify any
damaged windows to correct their cache data as well. Note that if you
change color depth (e.g. 8bpp to full color) dynamically that will
usually lead to the entire extended framebuffer being resent which can
take a long time over very slow links: it may be better to reconnect
and reset the format right after doing so.

smoother drags than tightvnc viewer. Response may also
be choppy if the server side machine is too slow.

Sometimes on very slow modem connections, this actually
gives an improvement because no pixel data at all
(not even the box animation) is sent during the drag.
