xorg-x11-server-1.19.5-5.1.el7

X.Org is an open-source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon.

This update adds the following enhancement:

* The X Window System specification describes a feature called "backing store", in which the X server attempts to preserve the pixel contents of windows which are occluded or unmapped. This enhancement implements backing store's "Always" mode, which is required by a number of applications and has also been implemented for Asianux Server 6. As a result, applications that require the Always mode now function correctly. (BZ#1627699)

Users of xorg-x11-server are advised to upgrade to these updated packages, which add this enhancement.
