Summary: Moderate: userspace graphics, xorg-x11, and mesa security, bug fix, and enhancement update

Details: 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. Mesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides hardware-accelerated drivers for many popular graphics chips. The following packages have been upgraded to a later upstream version: egl-wayland (1.1.5), libdrm (2.4.103), libglvnd (1.3.2), libinput (1.16.3), libwacom (1.6), mesa (20.3.3), xorg-x11-server (1.20.10).
