Philosophically speaking, neither a widget nor an application should
ever call XSync or XFlush.  XFlush gets called from the event loop or
when the data buffer is full.  Things usually refresh fastest if you
never explicitely XFlush.

There are exceptions, such as scrolling, that may make you want to
call XSync, but generally avoid it.
