19/08/2020 15:23:33 ------------------ USEFUL INFORMATION ------------------
19/08/2020 15:23:33 X DAMAGE available on display, using it for polling hints.
19/08/2020 15:23:33   To disable this behavior use: '-noxdamage'
19/08/2020 15:23:33
19/08/2020 15:23:33   Most compositing window managers like 'compiz' or 'beryl'
19/08/2020 15:23:33   cause X DAMAGE to fail, and so you may not see any screen
19/08/2020 15:23:33   updates via VNC.  Either disable 'compiz' (recommended) or
19/08/2020 15:23:33   supply the x11vnc '-noxdamage' command line option.
19/08/2020 15:23:33
19/08/2020 15:23:33 Wireframing: -wireframe mode is in effect for window moves.
19/08/2020 15:23:33   If this yields undesired behavior (poor response, painting
19/08/2020 15:23:33   errors, etc) it may be disabled:
19/08/2020 15:23:33    - use '-nowf' to disable wireframing completely.
19/08/2020 15:23:33    - use '-nowcr' to disable the Copy Rectangle after the
19/08/2020 15:23:33      moved window is released in the new position.
19/08/2020 15:23:33   Also see the -help entry for tuning parameters.
19/08/2020 15:23:33   You can press 3 Alt_L's (Left "Alt" key) in a row to
19/08/2020 15:23:33   repaint the screen, also see the -fixscreen option for
19/08/2020 15:23:33   periodic repaints.
19/08/2020 15:23:33
19/08/2020 15:23:33 XFIXES available on display, resetting cursor mode
19/08/2020 15:23:33   to: '-cursor most'.
19/08/2020 15:23:33   to disable this behavior use: '-cursor arrow'
19/08/2020 15:23:33   or '-noxfixes'.
19/08/2020 15:23:33 using XFIXES for cursor drawing.
19/08/2020 15:23:33 GrabServer control via XTEST.
19/08/2020 15:23:33
19/08/2020 15:23:33 Scroll Detection: -scrollcopyrect mode is in effect to
19/08/2020 15:23:33   use RECORD extension to try to detect scrolling windows
19/08/2020 15:23:33   (induced by either user keystroke or mouse input).
19/08/2020 15:23:33   If this yields undesired behavior (poor response, painting
19/08/2020 15:23:33   errors, etc) it may be disabled via: '-noscr'
19/08/2020 15:23:33   Also see the -help entry for tuning parameters.
19/08/2020 15:23:33   You can press 3 Alt_L's (Left "Alt" key) in a row to
19/08/2020 15:23:33   repaint the screen, also see the -fixscreen option for
19/08/2020 15:23:33   periodic repaints.
19/08/2020 15:23:33
19/08/2020 15:23:33 XKEYBOARD: number of keysyms per keycode 7 is greater
19/08/2020 15:23:33   than 4 and 51 keysyms are mapped above 4.
19/08/2020 15:23:33   Automatically switching to -xkb mode.
19/08/2020 15:23:33   If this makes the key mapping worse you can
19/08/2020 15:23:33   disable it with the "-noxkb" option.
19/08/2020 15:23:33   Also, remember "-remap DEAD" for accenting characters.
19/08/2020 15:23:33

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.
More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching
