Binary package “libxpresent1” in ubuntu hirsute

X11 Present extension library

 libXpresent provides an X Window System client interface to the Present
 extension to the X protocol.
 .
 The Present extension provides a way for applications to update their
 window contents from a pixmap in a well defined fashion, synchronizing
 with the display refresh and potentially using a more efficient
 mechanism than copying the contents of the source pixmap.
 .
