TightVNC, with which it remains compatible.  It contains a variant of Tight
encoding that is tuned to maximize performance for image-intensive
applications (such as VirtualGL, video applications, and image editors) while
still providing excellent performance for other types of applications.  Some
of its unique features are:
@itemize
@item a user-facing @command{vncserver} command;
@item the ability to capture keyboard keys even when not in full screen mode;
@item a full screen mode that is compatible with ratpoison*

*Although due to a quirk in Java, you'll want to set the
@env{_JAVA_AWT_WM_NONREPARENTING} environment variable when using it with
ratpoison.")
