magnus 1:1.0.3-2 (amd64 binary) in ubuntu impish

 Magnus is a simple screen magnifying glass. It nicely integrates with
 X11 desktops like MATE or Xfce (probably with others not named here,
 too).

 Visually impaired users may find this tool helpful for zooming into
 certain screen areas in order to improve readability/visibilty of fonts,
 icons and other data.
