03/02/2020 06:20:08   Most compositing window managers like 'compiz' or 'beryl',
03/02/2020 06:20:08   cause X DAMAGE to fail, and so you may not see any screen,
03/02/2020 06:20:08   updates via VNC.  Either disable 'compiz' (recommended) or,
03/02/2020 06:20:08   supply the x11vnc '-noxdamage' command line option.,
03/02/2020 06:20:08 X COMPOSITE available on display, using it for window polling.,
03/02/2020 06:20:08   To disable this behavior use: '-noxcomposite',

03/02/2020 06:20:08 Wireframing: -wireframe mode is in effect for window moves.,
03/02/2020 06:20:08   If this yields undesired behavior (poor response, painting,
03/02/2020 06:20:08   errors, etc) it may be disabled:,
03/02/2020 06:20:08    - use '-nowf' to disable wireframing completely.,
03/02/2020 06:20:08    - use '-nowcr' to disable the Copy Rectangle after the,
03/02/2020 06:20:08      moved window is released in the new position.,
03/02/2020 06:20:08   Also see the -help entry for tuning parameters.,

03/02/2020 06:20:08   (induced by either user keystroke or mouse input).,

03/02/2020 06:20:08   If this makes the key mapping worse you can,
03/02/2020 06:20:08   disable it with the "-noxkb" option.,

******************************************************************************,
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?,
,
The scheme stores pixel data offscreen on the VNC viewer side for faster,
retrieval.  It should work with any VNC viewer.  Try it by running:,
,
    x11vnc -ncache 10 ...,
,
One can also add -ncache_cr for smooth 'copyrect' window motion.,
