Description

Redraws the screen after it very likely has become garbled by some other output.

This should normally not be necessary: The ( specific ) UI redraws the screen automatically whenever required. Under rare circumstances, however, the screen might have changes due to circumstances beyond the UI's control: For text based UIs, for example, system commands that cause output to every tty might make this necessary. Call this in the YCP code after such a command.
